Perplexity Advanced Troubleshooting

Overview

Deep debugging for Perplexity Sonar API issues that resist standard fixes. Common hard problems: inconsistent citations between identical queries, intermittent timeouts on sonar-pro, search results not matching recency filter, and response quality degradation.

Prerequisites

Access to production logs and metrics
curl for direct API testing
Understanding of Perplexity's search-augmented generation model

Instructions
Variant 1: Direct Search Widget (<500 queries/day)
Best for: Adding AI search to an existing app. No cache needed at this scale.

// Simple endpoint — add to any Express/Next.js app
import OpenAI from "openai";

const perplexity = new OpenAI({
  apiKey: process.env.PERPLEXITY_API_KEY!,
  baseURL: "https://api.perplexity.ai",
});

app.post("/api/search", async (req, res) => {
  try {
    const response = await perplexity.chat.completions.create({
      model: "sonar",
      messages: [{ role: "user", content: req.body.query }],
      max_tokens: 1024,
    });

    res.json({
      answer: response.choices[0].message.content,
      citations: (response as any).citations || [],
    });
  } catch (err: any) {
    if (err.status === 429) {
      res.status(429).json({ error: "Rate limited. Try again shortly." });
    } else {
      res.status(500).json({ error: "Search unavailable" });
    }
  }
});

Variant 2: Cached Research Layer (500-5K queries/day)
Best for: Repeated queries, knowledge base search, FAQ bots. Cache eliminates duplicate API calls.

import { createHash } from "crypto";
import { LRUCache } from "lru-cache";

const cache = new LRUCache<string, any>({
  max: 5000,
  ttl: 4 * 3600_000,  // 4-hour TTL
});

class CachedSearchService {
  constructor(private client: OpenAI) {}

  async search(query: string, model = "sonar") {
    const key = this.cacheKey(query, model);
    const cached = cache.get(key);
    if (cached) return { ...cached, cached: true };

    const response = await this.client.chat.completions.create({
      model,
      messages: [{ role: "user", content: query }],
      max_tokens: 1024,
    });

    const result = {
      answer: response.choices[0].message.content || "",
      citations: (response as any).citations || [],
      model: response.model,
    };

    cache.set(key, result);
    return {

                  Perplexity CI Integration
Overview
Set up CI/CD pipelines for Perplexity Sonar API integrations. Key CI concerns: live API calls cost money (use mocks for unit tests, reserve live calls for integration tests), API keys must be in GitHub Secrets, and rate limits apply even in CI.
Prerequisites

GitHub repository with Actions enabled
Perplexity API key for CI (separate from production)
Test suite with mocked and live test separation

Instructions
Step 1: Configure GitHub Secret

set -euo pipefail
# Store API key as a GitHub secret
gh secret set PERPLEXITY_API_KEY --body "pplx-your-ci-key-here"

Step 2: GitHub Actions Workflow

# .github/workflows/perplexity-tests.yml

          cache: "npm"
      - run: npm ci
      - run: npm test -- --coverage
        # Unit tests use mocked responses — no API key needed

  integration-tests:
    runs-on: ubuntu-latest
    needs: unit-tests
    if: github.event_name == 'push' && github.ref == 'refs/heads/main'
    env:

      - run: npm ci
      - name: Run live Perplexity integration tests
        run: npm run test:integration
        timeout-minutes: 5

Step 3: Test Structure

// tests/perplexity.unit.test.ts — runs on every PR, uses mocks
import { describe, it, expect, vi } from "vitest";
import fixture from "./fixtures/sonar-response.json";

vi.mock("openai", () => ({

    chat: {
      completions: {
        create: vi.fn().mockResolvedValue(fixture),
      },
    },
  })),
}));

  it("parses citations from response", async () => {
    const { search } = await import("../src/perplexity/search");
    const result = await search("test query");
    expect(result.citations.length).toBeGreaterThan(0);
  });

  it("formats answer with citation links", async () => {
    const { formatCitationsAsMarkdown } = await import("../src/perplexity/citations");
    const formatted = formatCitationsAsMarkdown("See [1] for details", ["https://example.com"]);
    expect(formatted).toContain("[1](https://example.com)");
  });
});

Overview
Quick reference for the most common Perplexity Sonar API errors, their root causes, and fixes. All Perplexity errors follow the OpenAI error format since the API is OpenAI-compatible.
Prerequisites

PERPLEXITYAPIKEY environment variable set
curl available for diagnostic commands

Error Reference
401 Unauthorized — Invalid API Key

{"error": {"message": "Invalid API key", "type": "authentication_error", "code": 401}}

Causes: Key missing, expired, revoked, or doesn't start with pplx-.
Fix:

set -euo pipefail
# Verify key is set and has correct prefix
echo "${PERPLEXITY_API_KEY:0:5}"  # Should print "pplx-"

# Test key directly
curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer $PERPLEXITY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"sonar","messages":[{"role":"user","content":"test"}],"max_tokens":5}' \
  https://api.perplexity.ai/chat/completions
# 200 = valid, 401 = invalid key

Regenerate at perplexity.ai/settings/api.

429 Too Many Requests — Rate Limited

{"error": {"message": "Rate limit exceeded", "type": "rate_limit_error", "code": 429}}

Causes: Exceeded requests per minute (RPM). Most tiers allow 50 RPM. Perplexity uses a leaky bucket algorithm.
Fix:

async function withBackoff<T>(fn: () => Promise<T>, maxRetries = 5): Promise<T> {
  for (let i = 0; i <= maxRetries; i++) {
    try {
      return await fn();
    } catch (err: any) {
      if (err.status !== 429 || i === maxRetries) throw err;
      const delay = Math.pow(2, i) * 1000 + Math.random() * 500;
      console.log(`Rate limited. Retrying in ${delay.toFixed(0)}ms...`);
      await new Promise(r => setTimeout(r, delay));
    }
  }
  throw new Error("Unreachable");
}

See perplexity-rate-limits for queue-based solutions.

400 Bad Request — Invalid Model

{"error": {"message": "Invalid model: gpt-4", "type": "invalid_request_error"}}

Cause: Using a non-Perplexity model name.
Valid models: sonar, sonar-pro, sonar-reasoning-pro, sonar-deep-research.

Overview
Primary money-path workflow: send a search query to Perplexity Sonar, receive a web-grounded answer with inline citations, parse and display the results. This is the single-query pattern used for search widgets, fact-checking, and real-time information retrieval.
Prerequisites

Completed perplexity-install-auth setup
openai package installed
PERPLEXITYAPIKEY set

Instructions
Step 1: Initialize Client and Send Query

import OpenAI from "openai";

const perplexity = new OpenAI({
  apiKey: process.env.PERPLEXITY_API_KEY,
  baseURL: "https://api.perplexity.ai",
});

async function searchWithCitations(query: string) {
  const response = await perplexity.chat.completions.create({
    model: "sonar",
    messages: [
      {
        role: "system",
        content: "Provide accurate, well-sourced answers. Cite your sources inline.",
      },
      { role: "user", content: query },
    ],
    // Perplexity-specific parameters
    search_recency_filter: "week",  // hour | day | week | month
  } as any);

  return response;
}

Step 2: Parse Response with Citations

interface SearchResult {
  answer: string;
  citations: string[];
  searchResults: Array<{ title: string; url: string; snippet: string }>;
  tokensUsed: number;
}

function parseResponse(response: any): SearchResult {
  return {
    answer: response.choices[0].message.content,
    citations: response.citations || [],
    searchResults: response.search_results || [],
    tokensUsed: response.usage?.total_tokens || 0,
  };
}

Step 3: Format Citations for Display

function formatAnswer(result: SearchResult): string {
  let formatted = result.answer;

  // Replace [1], [2] markers with markdown links
  result.citations.forEach((url, i) => {
    formatted = formatted.replaceAll(`[${i + 1}]`, `[${i + 1}](${url})`);
  });

  // Append source list
  if (result.citations.length > 0) {
    formatted += "\n\n**Sources:**\n";
    result.citations.forEach((url, i) => {
      formatted += `${i + 1}. ${url}\n`;
    });
  }

  return formatted;
}

Step 4: Complete Workflow

async function main() {
  const query = "What are the latest advances in battery technology?";

  const response = await searchWithCitations(query);
  const result = parseResponse(response);
  const formatted = formatAnswer(result);

  console.log(formatted);
  console.log(`\n[${result.tokensUsed} tokens | ${result.citations.length} sources]`);
}

main().catch(console.error);

                  Perplexity Cost Tuning
Overview
Reduce Perplexity Sonar API costs. Perplexity charges per-token (input + output) plus a per-request fee that varies by search context size. The biggest cost lever is model selection: sonar-pro costs 3-15x more than sonar per request.
Pricing Reference

Search context size (Low/Medium/High) affects the request fee. More context = higher fee.
Prerequisites

Perplexity API account with usage dashboard
Understanding of query patterns in your application
Cache infrastructure for search results

Instructions
Step 1: Route Queries to the Right Model

// 60-70% of queries can use sonar, saving 3-15x per query
function selectModel(query: string): "sonar" | "sonar-pro" {
  const simplePatterns = [
    /^what is/i, /^define/i, /^who is/i, /^when did/i,
    /current price/i, /^how many/i, /^is it true/i,
  ];
  if (simplePatterns.some((p) => p.test(query))) return "sonar";

  const complexPatterns = [
    /compare.*vs/i, /analysis of/i, /comprehensive/i,
    /pros and cons/i, /in-depth/i, /research/i,
  ];
  if (complexPatterns.some((p) => p.test(query))) return "sonar-pro";

  return "sonar"; // Default to cheapest
}

Step 2: Limit Output Tokens

set -euo pipefail
# Factual queries need ~100 tokens, not 4096
# Setting max_tokens dramatically reduces output costs

                  Perplexity Data Handling
Overview
Manage data flowing through Perplexity Sonar API. Critical concern: queries are sent to Perplexity for web search, so any PII in queries is exposed to external infrastructure. Responses contain citations (third-party URLs) that must be validated before displaying to users.

Prerequisites

Perplexity API key configured
Understanding of PII regulations (GDPR/CCPA)
Cache storage (Redis or in-memory)

Instructions
Step 1: Query Sanitization

function sanitizeQuery(query: string): { clean: string; redacted: boolean } {
  let clean = query;
  let redacted = false;

  const patterns: Array<[RegExp, string]> = [
    [/\b[\w.+-]+@[\w-]+\.[\w.]+\b/g, "[email]"],
    [/\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/g, "[phone]"],
    [/\b\d{3}-\d{2}-\d{4}\b/g, "[ssn]"],
    [/\b\d{4}[\s-]?\d{4}[\s-]?\d{4}[\s-]?\d{4}\b/g, "[card]"],

    [/\b(user|customer|account)\s*#?\s*\d+\b/gi, "[id]"],
  ];

  for (const [pattern, replacement] of patterns) {
    if (pattern.test(clean)) {
      clean = clean.replace(pattern, replacement);
      redacted = true;
    }
  }

  return { clean, redacted };
}

async function safeSearch(rawQuery: string) {
  const { clean, redacted } = sanitizeQuery(rawQuery);
  if (redacted) {
    console.warn("[Data] PII redacted from Perplexity query");
  }

  return perplexity.chat.completions.create({
    model: "sonar",
    messages: [{ role: "user", content: clean }],
  });
}

Step 2: Citation Validation

interface ValidatedCitation {
  url: string;
  domain: string;
  valid: boolean;
  index: number;
}

function validateCitations(citations: string[]): ValidatedCitation[] {
  return citations.map((url, i) => {
    try {

      return {
        url: url.replace(/[.,;:]+$/, ""),
        domain: parsed.hostname,
        valid: ["http:", "https:"].includes(parsed.protocol),
        index: i + 1,
      };
    } catch {
      return { url, domain: "unknown", valid: false, index: i + 1 };
    }
  });

Overview
Control access to Perplexity Sonar API at the organizational level. Perplexity does not have built-in RBAC -- you implement access control through: separate API keys per team/environment, a gateway that enforces model and budget policies, and domain restrictions for compliance.
Access Control Strategy

Layer
Mechanism
Perplexity Support


Authentication
API key per team
Yes (multiple keys)


Model restriction
Gateway enforcement

Rate limiting
Gateway + key limits
Yes (per-key RPM)


Prerequisites

Perplexity API account with admin access
Separate API keys per team/environment
Gateway or middleware for policy enforcement

Instructions
Step 1: Create Per-Team API Keys
Generate separate keys at perplexity.ai/settings/api:

Key: pplx-support-bot-prod     → Budget: $200/mo, sonar only
Key: pplx-research-team        → Budget: $1000/mo, sonar + sonar-pro
Key: pplx-data-team            → Budget: $500/mo, sonar only
Key: pplx-executive-reports    → Budget: $300/mo, sonar-pro

                  Perplexity Install & Auth
Overview
Set up Perplexity Sonar API access using the OpenAI-compatible chat completions endpoint at https://api.perplexity.ai. Perplexity does not have a custom SDK -- you use the standard OpenAI client library pointed at Perplexity's base URL.
Prerequisites

Node.js 18+ or Python 3.10+
Perplexity account at perplexity.ai
API key from perplexity.ai/settings/api

Instructions
Step 1: Install OpenAI Client Library

set -euo pipefail
# Node.js / TypeScript
npm install openai

# Python
pip install openai

There is no @perplexity/sdk package. Perplexity uses the OpenAI wire format, so you use the official openai package with a custom baseURL.
Step 2: Configure API Key

# Set environment variable
export PERPLEXITY_API_KEY="pplx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

# Or create .env file (add .env to .gitignore)
echo 'PERPLEXITY_API_KEY=pplx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' >> .env

API keys start with pplx- and are generated at perplexity.ai/settings/api. You must add credits to your account before making API calls.
Step 3: Verify Connection (TypeScript)

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.PERPLEXITY_API_KEY,
  baseURL: "https://api.perplexity.ai",
});

async function verify() {
  const response = await client.chat.completions.create({
    model: "sonar",
    messages: [{ role: "user", content: "What is 2+2?" }],
    max_tokens: 50,
  });
  console.log("Connected:", response.choices[0].message.content);
  console.log("Model:", response.model);
  console.log("Tokens used:", response.usage?.total_tokens);
}

verify().catch(console.error);

Step 4: Verify Connection (Python)

                  Perplexity Known Pitfalls
Overview
Real gotchas when integrating Perplexity Sonar API. Perplexity uses an OpenAI-compatible chat endpoint but performs live web searches -- a fundamentally different paradigm from standard LLM completions. These pitfalls come from treating it like a regular chatbot.
Prerequisites

Perplexity API key configured
Understanding of OpenAI-compatible chat API format

Pitfalls
1. Using It as a Generic Chatbot
Perplexity searches the web per request. Using it for tasks that don't need web search wastes money.

# BAD: general chatbot (wastes a search query)
response = call_perplexity("Write me a haiku about cats")
# Costs $0.005+ for something any LLM can do offline

# GOOD: leverage web search capability
response = call_perplexity(
    "What are the latest Next.js 15 features released this month?",
    search_recency_filter="month"
)

2. Ignoring Citations
Perplexity returns [1], [2] markers in text with a separate citations array. Ignoring them loses the key value prop.

data = response.model_dump()  # or response.json() for raw HTTP
answer = data["choices"][0]["message"]["content"]
citations = data.get("citations", [])  # NOT in choices — top-level field

# BAD: displaying raw markers
print(answer)  # "According to [1], Node.js 22 adds..."

# GOOD: replace markers with links
import re
for i, url in enumerate(citations, 1):
    answer = answer.replace(f"[{i}]", f"[{i}]({url})")

3. Using Wrong SDK Import
There is no @perplexity/sdk or perplexity Python package. Use the standard OpenAI client.

// BAD — this package doesn't exist
import { PerplexityClient } from "@perplexity/sdk";

// GOOD — use OpenAI client with Perplexity base URL
import OpenAI from "openai";
const client = new OpenAI({
  apiKey: process.env.PERPLEXITY_API_KEY,
  baseURL: "https://api.perplexity.ai",
});

4. Not Setting max_tokens
Without max_tokens, responses can be arbitrarily long, increasing costs unpredictably.

// BAD: no token limit — output cost can spike
await client.chat.completions.create({
  model: "sonar-pro",  // $15/M output tokens!
  messages: [{ role: "user", content: "Tell me about AI" }],
});

// GOOD: always set max_tokens
await client.chat.completions.create({
  model: "sonar-pro",
  messages: [{ role: "user", content: "Tell me about AI" }],
  max_tokens: 1024,
});

5. No Recency Filter for Time-Sensitive Queries
Without searchrecency

Overview
Complete checklist for deploying Perplexity Sonar API integrations to production. Perplexity-specific concerns: every API call performs a live web search (variable latency), citations link to third-party sites (must validate), and costs scale per-request plus per-token.
Prerequisites

Staging environment tested
Production API key generated (separate from dev/staging)
Monitoring configured
Cost budget defined

Production Readiness Checklist
API Configuration

[ ] Production PERPLEXITYAPIKEY in secret manager (not env file)
[ ] Key starts with pplx- and has credits loaded
[ ] Separate API keys for dev/staging/prod
[ ] Base URL is https://api.perplexity.ai (not localhost/proxy)
[ ] Model selection configured: sonar for fast, sonar-pro for deep

Code Quality

[ ] All search calls wrapped in retry with exponential backoff
[ ] Rate limiting implemented (50 RPM default)
[ ] Query sanitization strips PII before sending to Perplexity
[ ] Citations parsed from response (not extracted from text)
[ ] max_tokens set on all requests (prevents runaway costs)
[ ] Timeouts configured: 15s for sonar, 30s for sonar-pro
[ ] Error handling covers 401, 402, 429, 500+ status codes
[ ] No hardcoded API keys in source code

Performance

[ ] Result caching implemented for repeated queries
[ ] Cache TTL appropriate: 30min for news, 4hrs for research, 24hrs for facts
[ ] Streaming enabled for user-facing search (reduces perceived latency)
[ ] Request queue prevents burst overload
[ ] searchdomainfilter used where appropriate (reduces search time)

Monitoring

[ ] Latency tracked per model (sonar ~2s, sonar-pro ~5s, deep-research ~30s)
[ ] Error rate monitored (alert on >5% failure rate)
[ ] Token usage tracked for cost projection
[ ] Citation count per response logged (quality signal)
[ ] 429 rate limit errors tracked with alert

Cost Controls

[ ] Monthly budget cap set on API key
[ ] Model routing: simple queries to sonar, complex to sonar-pro
[ ] max_tokens capped per endpoint
[ ] Cache hit rate monitored (target >30%)
[ ] Cost per query tracked by model

Graceful Degradation

// Validate key format at startup
function validateApiKey(key: string): void {
  if (!key) throw new Error("PERPLEXITY_API_KEY is not set");
  if (!key.startsWith("pplx-")) {
    throw new Error("PERPLEXITY_API_KEY must start with 'pplx-'");
  }
  if (key.length < 40) {
    throw new Error("PERPLEXITY_API_KEY appears truncated");
  }
}

validateApiKey(process.env.PERPLEXITY_API_KEY || "");

Step 2: Query Sanitization (Critical)
Perplexity sends your query to the open web for search. Any PII in the query is exposed to external search infrastructure.

function sanitizeQuery(query: string): string {
  return query
    // Remove email addresses
    .replace(/\b[\w.+-]+@[\w-]+\.[\w.]+\b/g, "[email]")
    // Remove phone numbers
    .replace(/\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/g, "[phone]")
    // Remove SSN
    .replace(/\b\d{3}-\d{2}-\d{4}\b/g, "[ssn]")
    // Remove credit card numbers
    .replace(/\b\d{4}[\s-]?\d{4}[\s-]?\d{4}[\s-]?\d{4}\b/g, "[card]")
    // Remove API keys / tokens
    .replace(/\b(pplx-|sk-|pk_|sk_live_)\w{20,}\b/g, "[token]")
    // Remove AWS keys
    .replace(/\bAKIA[A-Z0-9]{16}\b/g, "[aws-key]");
}

async function safeSearch(rawQuery: string) {
  const query = sanitizeQuery(rawQuery);
  if (query !== rawQuery) {
    console.warn("[Security] PII redacted from Perplexity query");
  }

  return perplexity.chat.completions.create({
    model: "sonar",
    messages: [{ role: "user", content: query }],
  });
}

Step 3: Restrict Search Domains
Use searchdomainfilter to prevent Perplexity from searching untrusted or competitor sites.

// Compliance: only search approved sources
const complianceSearch = await perplexity.chat.completions.create({
  model: "sonar",
  messages: [{ role: "user", content: query }],
  search_domain_filter: [

Overview
Guide for migrating between Perplexity model generations and API changes. Perplexity has evolved from pplx-api with third-party models to the Sonar family with built-in web search.
Model Evolution

Era
Models

Instructions
Step 1: Identify Legacy Patterns to Update

set -euo pipefail
# Find deprecated model names in your codebase
grep -rn "pplx-7b\|pplx-70b\|llama.*sonar\|sonar-small\|sonar-medium\|sonar-huge" \
  --include="*.ts" --include="*.py" --include="*.js" --include="*.json" \
  . 2>/dev/null || echo "No legacy models found"

# Find old base URLs
grep -rn "api.perplexity.com\|pplx.readme.io" \
  --include="*.ts" --include="*.py" --include="*.js" \
  . 2>/dev/null || echo "No legacy URLs found"

Step 2: Model Name Migration Map

// Migration map: old model name -> new model name
const MODEL_MIGRATION: Record<string, string> = {
  // Legacy pplx-api models (fully deprecated)
  "pplx-7b-online": "sonar",
  "pplx-70b-online": "sonar-pro",

                  Perplexity Events & Async Patterns
Overview
Build event-driven architectures around Perplexity Sonar API. Perplexity does not have webhooks -- all interactions are request/response. Event patterns are built using streaming SSE, job queues for batch processing, and cron-triggered monitoring.
Event Patterns

Pattern
Trigger
Use Case


Streaming SSE
Client request
Real-time search with progressive rendering


Batch queue
Job submission
Research automation, report generation


Scheduled search
Cron job
News monitoring, trend alerts, competitive intel


Citation pipeline
Post-processing
Source verification, link validation


Prerequisites

openai package installed
PERPLEXITYAPIKEY set
Queue system (BullMQ, SQS) for batch patterns
Cron scheduler for monitoring patterns

Instructions
Step 1: Streaming Search (Server-Sent Events)

import OpenAI from "openai";
import express from "express";

const perplexity = new OpenAI({
  apiKey: process.env.PERPLEXITY_API_KEY!,
  baseURL: "https://api.perplexity.ai",
});

const app = express();
app.use(express.json());

app.post("/api/search/stream", async (req, res) => {
  const { query, model = "sonar" } = req.body;

  res.writeHead(200, {
    "Content-Type": "text/event-stream",
    "Cache-Control": "no-cache",
    Connection: "keep-alive",
  });

  try {
    const stream = await perplexity.chat.completions.create({
      model,
      messages: [{ role: "user", content: query }],
      stream: true,
      max_tokens: 2048,
    });

    let fullText = "";
    for await (const chunk of stream) {
      const text = chunk.choices[0]?.delta?.content || "";
      fullText += text;

      res.write(`data: ${JSON.stringify({ type: "text", content: text })}\n\n`);

      // Citations arrive in the final chunk
      const citations = (chunk as any).citations;
      if (citations) {
        res.write(`data: ${JSON.stringify({ type: "citations", urls: citations })}\n\n`);
      }
    }

    res.write(`data: ${JSON.stringify({ type: "done", totalLength: fullText.length })}\n\n`);
  } catch (err: any) {
    res.write(`data: ${JSON.stringify({ type: "error", message: err.message })}\n\n`);
  }

  res.end();
});

Step 2: Batch Research Pipeline

import { Queue, Worker } from "bullmq";

const searchQueue = new Queue("perplexity-research", {
  connection: { host: "localhost", port: 6379

                

              

          

        

      
      
          How It Works
          
import OpenAI from "openai";

const perplexity = new OpenAI({
  apiKey: process.env.PERPLEXITY_API_KEY,
  baseURL: "https://api.perplexity.ai",
});

const response = await perplexity.chat.completions.create({
  model: "sonar",
  messages: [{ role: "user", content: "What are the latest AI developments?" }],
});

console.log(response.choices[0].message.content);
console.log("Sources:", (response as any).citations);
