Dify version

0.6.5

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I have implemented my own plugin with simple bearer authorization. I tested it's usable in the tool panel, but when using it in an agent, there's a chance the tool call fails due to 401 Unauthorized. It's really weird, since sometimes the tool call succeeds.

You can try with a simple plugin with a python backend. Or, I can share my plugin with you since it's just a demo only for testing.

I've check the logs in the api server(see below screenshot). The first 4 calls are produced by an agent I develop. The last two was produced by my testing in the tool panel with the same arguments, no modifications on authorizations.

✔️ Expected Behavior

Smooth tool calls when agents try to call a tool with correct authorization

❌ Actual Behavior
