Troubleshooting

Common Issues

1. API Key Not Set
   • Ensure GOPHER_API environment variable is set
   • Verify the API key is valid and has proper permissions
2. Search Timeout
   • The server polls for results up to 30 times (60 seconds total)
   • Check if the Gopher AI service is experiencing delays
