Gamma Common Errors

Overview

Reference guide for debugging and resolving common Gamma API errors.

Prerequisites

  • Active Gamma integration
  • Access to logs and error messages
  • Understanding of HTTP status codes

Error Reference

Authentication Errors (401/403)

typescript
// Error: Invalid API Key
{
  "error": "unauthorized",
  "message": "Invalid or expired API key"
}
Solutions:
  1. Verify API key in Gamma dashboard
  2. Check environment variable is set: 
    echo $GAMMA_API_KEY
  3. Ensure key hasn't been rotated
  4. Check for trailing whitespace in key

Rate Limit Errors (429)

typescript
// Error: Rate Limited
{
  "error": "rate_limited",
  "message": "Too many requests",
  "retry_after": 60
}
Solutions:
  1. Implement exponential backoff
  2. Check rate limit headers: 
    X-RateLimit-Remaining
  3. Upgrade plan for higher limits
  4. Queue requests with delays
typescript
async function withRetry(fn: () => Promise<any>, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (err) {
      if (err.code === 'rate_limited' && i < maxRetries - 1) {
        const delay = (err.retryAfter || Math.pow(2, i)) * 1000;
        await new Promise(r => setTimeout(r, delay));
        continue;
      }
      throw err;
    }
  }
}

Generation Errors (400/500)

typescript
// Error: Generation Failed
{
  "error": "generation_failed",
  "message": "Unable to generate presentation",
  "details": "Content too complex"
}
Solutions:
  1. Simplify prompt or reduce slide count
  2. Remove special characters from content
  3. Check content length limits
  4. Try different style setting

Timeout Errors

typescript
// Error: Request Timeout
{
  "error": "timeout",
  "message": "Request timed out after 30000ms"
}
Solutions:
  1. Increase client timeout setting
  2. Use async job pattern for large presentations
  3. Check network connectivity
  4. Reduce request complexity
typescript
const gamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY,
  timeout: 60000, // 60 seconds
});

Export Errors

typescript
// Error: Export Failed
{
  "error": "export_failed",
  "message": "Unable to export presentation",
  "format": "pdf"
}
Solutions:
  1. Verify presentation exists and is complete
  2. Check supported export formats
  3. Ensure no pending generation jobs
  4. Try exporting with lower quality setting

Debugging Tools

Enable Debug Logging

typescript
const gamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY,
  debug: true, // Logs all requests/responses
});

Check API Status

typescript
const status = await gamma.status();
console.log('API Status:', status.healthy ? 'OK' : 'Issues');
console.log('Services:', status.services);

Error Handling Pattern

typescript
import { GammaError, RateLimitError, AuthError } from '@gamma/sdk';

try {
  const result = await gamma.presentations.create({ ... });
} catch (err) {
  if (err instanceof AuthError) {
    console.error('Check your API key');
  } else if (err instanceof RateLimitError) {
    console.error(`Retry after ${err.retryAfter}s`);
  } else if (err instanceof GammaError) {
    console.error('API Error:', err.message);
  } else {
    throw err;
  }
}
