Debug not working in Visual Studio Code for Func App with Python

Question

I am testing the VS Code's built-in HttpTrigger in Win 10, which is working, but the debugging is not working (breakpoints are not paused).

Below is the logging when starting Run -> Start Debugging.

connect econnrefused 127.0.0.1:9091

It processes the request successfully, but no breakpoints are paused.

Executing task: .venv\Scripts\python -m pip install -r requirements.txt <

Requirement already satisfied: azure-functions in c:.me\mylab.code\azurecode\functions\funcpython\app.venv\lib\site-packages (from -r requirements.txt (line 5)) (1.11.2)

Terminal will be reused by tasks, press any key to close it.

Executing task: func host start <

Found Python version 3.9.13 (py).

What I tried:

Environment:

Azure Func core tool: 3.0.4626

Function Runtime Version: 3.9.0.0

https://go.microsoft.com/fwlink/?linkid=2135274 https://github.com/Azure/azure-functions-core-tools

VS Code: Version 1.69

Python: 3.9.13

Python extension: v2022.10.1

Azure Functions extension: v1.7.4

Answer 1

After I updated relevant extensions, it works now.

Examples of the extensions (not all) might be relevant:

Azure Function: 1.7.4

Jupyter: 2022.6.12

Pylance: 2022.7.40

Python: 2022.10.1

There might be more extensions for you to update. Try to resolve all relevant extension updates if possible.
