Description
During Local Debugging on Python Azure Functions, I get an Error saying.
Warning
The operation was aborted. Rejecting from abort signal callback while making request.
However, the process of Debugging works as usual after the Error. I am able to Continue, Step Into, Step Over etc. as usual in the Debug mode.
Steps to reproduce
Here is what I did.
- Setup Azure Function environment on Local System.
- Setup Python without a Virtual Environment (Skip Virtual Environment).
- Create a HTTP Trigger Function http_trigger with the Default Configuration.
- Set a Breakpoint at Line Number 10.
- Start Local Debugging using Fn + F5.
- Execute the HTTP Function http_trigger from the Local Project.
- Got the Error after ~10 seconds.

Hi, Eleanor Boyd (@eleanorjboyd)
Should I follow the instructions here to Enable debugger logs or is there some other article that I can refer?
I am sharing screenshots of the Visual Studio Code tabs captured after I repeated the process today.

I don't believe this is a debugger error. The 'source' of the error is Azure Functions. Something there is putting up this message.

My guess is that pausing in the debugger causes whatever is listening for that azure function to timeout.
