Hi @RERRRER! I'm Dosu and I’m helping the dify team.

This error is a known issue in Dify 1.4.1 and has been fixed in a recent update. To resolve it, uninstall and reinstall the affected plugins—no additional configuration or image updates are needed, as the underlying problem was patched on the marketplace side. If you’re running both the source code and Docker at the same time, stop one to avoid data conflicts. If the error persists, clean your database to remove conflicting provider records, or do a full database purge and fresh install. For plugin initialization timeouts, you can add PYTHON_ENV_INIT_TIMEOUT to your docker-compose.yaml as needed. For more details, see the related issues: #20448, #20445, and #15940.

To reply, just mention @dosu.

@RERRRER commented on GitHub (Jun 9, 2025):

All the above methods have been tried, including deleting the plugin data directory, changing the PIP mirror source, modifying FORCE_VERIFYING_SIGNATURE=false, adding PYTHON_ENV_INIT_TIMEOUT=320, and other plugins can be installed normally. However, the two plugins langgenius/tongyi and junjiem/mcp_compat_dify_tools still fail to install properly, showing the error "PluginDaemonInternalServerError: plugin not found".

I've fixed these plugins, you can try installing them again.
