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)

// 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)

// 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

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;  # 1000: 1 second in ms
        await new Promise(r => setTimeout(r, delay));
        continue;
      }
      throw err;
    }
  }
}

Generation Errors (400/500)

// 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

// 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

const gamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY,
  timeout: 60000, // 60 seconds  # 60000: 1 minute in ms
});

Export Errors

// 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

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

Check API Status

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

Error Handling Pattern

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;
  }
}
