[Python] connect ECONNREFUSED error: How do I use debugger on a python function in VSCode when...

How do I get debugger to run on my function in VSCode with this as my launch.json and task.json (respectively) when I use type shell on a task?

launch.json

task.json

When I run debugger on this, I get the "connect ECONNREFUSED 127.0.0.1:9091" error.

When I run debugger with type "func" it works as normal and it stops at breakpoints and terminates without errors.

task.json

The only difference between functional and "connection refused" is having the type as "func" or type as "shell" in my tasks.json.

Is it possible that a type "shell" task has a different default port?

Any suggestions to fix this is appreciated, thank you!


Goal of what I'm trying to do...:

I've created an Azure function in Python on VSCode. It works and the debugger worked as well after I added a .vscode folder. I need a virtual environment so I can ensure consistency between me and other people or setups which could be working on this. To do this, I use pipenv. "pipenv shell" and "pipenv run func host start" both work fine when I use powershell/cmd terminal in VSCode. The problem is when I try to use the VSCode debugger on this.

I was trying to use a type "shell" task with the command being "pipenv run func host start" when I stumbled on this error with the debugger. This command works when I enter it into the vscode terminal(powershell). When I put this into task.json however, it gave me a connection refused error on the port. As stated above, this works fine when I use type "func" instead of "shell", however a type "func" does not allow me to run pipenv.

After some tests and reading stack overflow solutions, I narrowed this connection refusal to just the change between type "func" or "shell".
