Debugging Python in Docker

[JanPalasek]

I created a sample project using Docker > Add Docker Files to Workspace.

Then I ran Ctrl + F5, it correctly builds the image but then it raises an error that I can't get rid of:

Invalid message: "pythonPath" is not valid if "python" is specified.

Here is the sample project. I left everything default, just added app.py with a hello world message.

test.zip

Versions

• System: Windows 11 using WSL 2 on Ubuntu 20.04.
• Docker vscode: v1.23.3
• Python vscode: v2023.2.0

Started seeing this too in VSCode 1.75.
Downgrading to 1.74 makes it go away (but that's not a solution)

I am also having this same issue and I found there is an open issue on the vscode repo as well.

microsoft/vscode#173319

Did this issue start happening recently, or has it been a few weeks? It might be a Python extension issue.

Same problem here on v1.75, last week my docker project was running without any problems. No updates on python since then, maybe auto-update on VSCode.

VSCode: 1.75
Python: 3.10.9
Mac: 13.2

No updates on Docker extension since 19 December; Python extension was updated today, and IIRC sometime last week as well. So I think it's something between VSCode and/or Python extension.

Same issue here
vscode 1.75
Windows 10

It works after downgrading vscode to 1.74 and reinstall python extension

Reported here as well

Same here, it had version 1.75. Windows 11.

I fixed it by downgrading to 1.74 (and reinstall Python Extension)

Same problem here. It was working fine 10 minutes ago. I had to restart VS Code due to a crash, and it decided to update. Now I get this error.

Same error here. It suddenly decided to stop working after the update.
