Troubleshooting

Extension Not Appearing

• Verify installation in custom_nodes/ComfyUI-Majoor-AssetsManager
• Check ComfyUI console for import errors
• Ensure all dependencies are installed: pip install -r requirements.txt
• Restart ComfyUI completely

Database Corruption

If the index database is corrupted:

Option 1: Use Delete DB Button (Recommended)

1. Open Assets Manager → Index Status section
2. Click Delete DB button
3. Confirm the warning dialog
4. Database rebuilds automatically

Option 2: Manual Recovery

1. Stop ComfyUI completely
2. Navigate to <output>/_mjr_index/
3. Delete assets.sqlite, assets.sqlite-wal, assets.sqlite-shm
4. Restart ComfyUI

See docs/DB_MAINTENANCE.md for detailed recovery procedures.

External Tools Not Found

• Verify installation: exiftool -ver and ffprobe -version
• Check if tools are in system PATH
• Set environment variables for explicit paths
• Restart ComfyUI after installing tools

Slow Performance

• First scan of large directories takes time (incremental indexing helps)
• Reduce page size in settings for lower memory usage
• Exclude very large directories from custom roots
• Ensure SSD storage for better database performance

Search Not Working

• Trigger manual scan with Ctrl+S
• Verify the correct scope is selected
• Check if directory has been indexed (status indicator)
• Clear browser cache and reload

Drag & Drop Issues

• Verify browser supports HTML5 drag & drop
• Check file permissions for source files
• For multi-select ZIP, ensure sufficient disk space
• Try a different browser if issues persist

API / Remote Access

• Set MAJOOR_API_TOKEN for secure remote access
• Configure MAJOOR_TRUSTED_PROXIES if behind reverse proxy
• Check firewall settings for ComfyUI port
• Verify CORS settings if accessing from different origin
