Application is getting hanged while holding and terminating BidiAppend request

[nithesh_chandra]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

While using agent mode in cursor ide, sending a prompt,when we are terminating the BidiAppend packet in the request itself, the prompt response window gets hanged in cursor ide native app.

How can we gracefully terminate the session by intimating the cursor client that it does not get hanged

Steps to Reproduce

Open cursor ide in windows native, press ctrl+L .
Then type a prompt in agent mode, there will be request originated to endpoint BidiAppend.

Terminate that request in between , the app chat window gets hanged.

Expected Behavior

When we terminate the request transaction, the app should not get hanged.

Yes still issue is same..
what i understood is when i sent prompt in the chat.
2 requests and sessions (on different ports) from cursor client got initiated , one which carries the prompt and the other one is which brings back the response from server.

Here issue comes for the hang. , when prompt packet got terminated. Cursor client goes into hanged state in this scenario.
