Versions

1. dify-plugin-daemon Version: latest main branch (langgenius/dify-plugin-daemon:main-local)
2. dify-api Version: 1.13.2

Describe the bug

This is a re-opened issue of #646.
I've tested the main branch AFTER #648 and confirmed that the issue still exists.

In PRs #624 and #644, the code was changed so that manually_uploaded key is set inside UploadPluginPkg, and uv uses the --offline option.

However, the /install/upload/package endpoint, where UploadPluginPkg is executed, is also called when installing plugins from the marketplace (after the API container downloads the plugin, it uploads it to this endpoint).

As a result, plugins can no longer be installed from the marketplace.

To Reproduce
Steps to reproduce the behavior:

1. Deploy fresh Dify 1.13.2 instance
2. Switch plugin daemon to use langgenius/dify-plugin-daemon:main-local
3. Try installing any plugins from marketplace
4. Got error on the Web UI.

Expected behavior
Plugin can be installed without any issue.
