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, 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) ```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 # 60000: 1 minute in ms }); ``` ### 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; } } ``` ## Resources - [Gamma Status Page](https://status.gamma.app) - [Gamma Error Codes](https://gamma.app/docs/errors) - [Gamma Support](https://gamma.app/support) ## Next Steps Proceed to `gamma-debug-bundle` for comprehensive debugging tools. --- Source attribution: jeremylongshore Original project: https://github.com/jeremylongshore/claude-code-plugins-plus-skills/blob/main/plugins/saas-packs/gamma-pack/skills/gamma-common-errors/SKILL.md License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice MIT License Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
