Common issues

​
Custom git executable path

If your git.exe is installed in a specific location other than the system default:

  2. Open <USER_DIRECTORY>/default/ComfyUI-Manager/config.ini
  3. Specify the full path including the file name in git_exe =

Scanner troubleshooting

When running the scan.sh script:
  • It updates extension-node-map.json by pulling or cloning custom nodes listed in custom-node-list.json into ~/.tmp/default
  • It updates github-stats.json using the GitHub API
To avoid GitHub API rate limits, set your token: export GITHUB_TOKEN=your_token_here
If you want to specify a different path instead of ~/.tmp/default, run python scanner.py [path] directly instead of scan.sh.

​
Security policy

If you encounter the error This action is not allowed with this security level configuration when installing custom nodes via git URL or using the nightly version, you need to adjust the security level in your config.ini file. The config.ini file is located at:
  • ComfyUI v0.3.76+: <USER_DIRECTORY>/__manager/config.ini
  • Older versions: <USER_DIRECTORY>/default/ComfyUI-Manager/config.ini
Where <USER_DIRECTORY> defaults to ComfyUI/user. See Configuration for more details. Configure security levels in config.ini:

​
Risk levels for features

To install custom nodes via git URL or nightly versions, set security_level = weak in your config.ini.
