Originally created by @sergik86 on GitHub (May 30, 2025).

Description:

I’m developing a plugin for Dify version 1.4.1, implemented as an Endpoint class. In the plugin code, I try to call self.session.app.chat.invoke(...), passing the app_id from the plugin settings and using a token obtained from the Plugin Debug tool.

However, the call fails with the error:

{
  "message": "Internal Server Error",
  "code": "unknown"
}

In the Dify API container logs, I see this message:

Exception: Invalid Authorization token.

Steps to reproduce:

  • Create a Python plugin with an Endpoint class.
  • In the _invoke method, call self.session.app.chat.invoke(...) using the app_id from settings and the token from Plugin Debug.
  • Send a request to the plugin (e.g., via Mattermost).
  • Receive a 500 error and the "Invalid Authorization token" message in logs.

Expected behavior:

  • The plugin should successfully invoke the specified app using the token.

Actual behavior:

  • The invocation fails with a 500 error and "Invalid Authorization token" in logs, although the token was taken from Plugin Debug.

Environment info:

  • Dify version: 1.4.1
  • Plugin type: Python Endpoint
  • Deployment: local (docker)
  • dify_plugin>=0.2.0,<0.3.0

Additional notes:

  • It seems the token provided by Plugin Debug is not suitable for calling app.chat.invoke from the plugin.
  • It would be helpful if the error returned a more informative status (e.g., 401 Unauthorized).
  • Please clarify in the docs which token should be used and how to properly call app.chat.invoke from a plugin.
