I believe I understand the issue. It generates a model_manager.sqlite file in the root directory, but there are no permissions granted on the cloud version.

Hi, @skyheming. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You reported that enabling the ComfyUI-Sentinel API key causes image generation workflows to fail with an "OperationalError: unable to open database file."
  • The issue seems related to the plugin creating a model_manager.sqlite file in the root directory without proper permissions, especially on the cloud version.
  • Maintainer hjlarry identified the problem as database file access restrictions introduced by the Sentinel plugin.
  • No resolution has been provided yet, and the problem persists.

Next Steps:

  • Please let me know if this issue is still relevant with the latest version of the dify-official-plugins repository by commenting here.
  • If I do not hear back within 5 days, I will automatically close this issue.

Thank you for your understanding and contribution!
