Troubleshooting

Common Issues

Issue: Agent creation failed

Symptoms: API error when creating voice agent Cause: Invalid configuration, missing fields, or API issue Solution:

Validate agent config JSON format
Ensure all required fields are present (name, first_message, system_prompt)
Check prompt length doesn't exceed limits
Review ElevenLabs API documentation for requirements

Issue: Invalid voice ID

Symptoms: "Voice not found" or "invalid voice_id" error Cause: Voice ID doesn't exist or not accessible Solution:

Use valid ElevenLabs voice ID from your library
Check voice availability at https://elevenlabs.io/app/voice-library
Verify voice is not a custom voice from another account
Use default voice if custom voice unavailable

Issue: API quota exceeded

Symptoms: "Quota exceeded" or rate limit error Cause: ElevenLabs subscription limits reached Solution:

Check usage at https://elevenlabs.io/app/subscription
Upgrade subscription tier for more capacity
Reduce number of concurrent agents
Delete unused agents to free up slots

Issue: Agent not responding in calls

Symptoms: Agent created but doesn't respond in conversations Cause: System prompt issues, webhook configuration, or service issue Solution:

Test agent directly in ElevenLabs console first
Review system prompt for clear instructions
Check webhook URL is accessible (if configured)
Verify ElevenLabs service status

Issue: OpenRouter prompt generation failed

Symptoms: Error generating agent prompt Cause: OpenRouter API issue or invalid model Solution:

Verify OPENROUTER_API_KEY is set correctly
Check model availability at OpenRouter
Try a different model if current one unavailable
Run with --dry-run to test without API calls

Issue: Google Drive context not loading

Symptoms: Agent created without client context Cause: OAuth issue or client folder not found Solution:

Verify Google OAuth credentials (see google-workspace skill)
Check client folder exists in expected location
Provide context via --notes flag as alternative
Run without context enrichment first to isolate issue
