Platform's log shows 400 status

[MingoLau]

I have done these:

1. setup.bat→enter→enter→enter
2. enter into the 'platform container', run 'poetry install'
3. open localhost:3000, input an api-key and user's email

But when I click 'tool settings', the page shows 'error loading tools', and I found these abnormal note in the container log:
INFO | logging:callHandlers:1706 - 172.18.0.1:43400 - "OPTIONS /api/agent/tools HTTP/1.1" 400
INFO | logging:callHandlers:1706 - 172.18.0.1:53580 - "OPTIONS /api/agent/tools HTTP/1.1" 400

I think the deep reason is about the platform, so that the frontend couldn't request the platform's resources. How can I fix this problem?
