Troubleshooting

Solve common issues when analyzing n8n workflows:

Analysis doesn't recognize n8n-specific patterns

The analysis is too generic and missing n8n-specific insights.

  • Ensure you're using a valid n8n workflow JSON export
  • Use "comprehensive" analysis depth for better n8n understanding
  • Enable alternative node suggestions for n8n-specific recommendations
  • Include workflow descriptions and node notes in your export
JSON file format errors

Getting errors about invalid JSON or file format issues.

  • Export workflows using n8n's built-in export feature (not copy-paste)
  • Verify the JSON file is valid using a JSON validator
  • Check file permissions and path accessibility
  • Try using the workflow parameter instead of filePath
Missing performance recommendations

Not getting specific performance optimization suggestions.

  • Set optimizationFocus to "performance" for targeted analysis
  • Use "comprehensive" analysis depth for detailed performance insights
  • Ensure workflows have sufficient complexity to analyze (simple workflows may not need optimization)
  • Include node execution data if available from n8n logs
Credential security warnings

Getting warnings about credential exposure or security issues.

  • Remove any hardcoded credentials or sensitive data from workflow exports
  • Use n8n's credential system instead of inline secrets
  • Set includeCredentialCheck to false if analyzing test workflows only
  • Review data handling practices in HTTP and database nodes
Large workflow analysis takes too long

Analysis of complex workflows with many nodes is slow or times out.

  • Start with "basic" analysis depth for initial overview
  • Focus on specific optimization areas rather than "all"
  • Analyze workflow sections separately if they're modular
  • Ensure your LM Studio model has sufficient memory for large JSON processing
