Error while enumerating installed pacages when trying to remote attach from VS code

I am a newbie to Slicer extension development and tried to set up python debugging with vs code following the github instruction. But I got the error as shown below in the Slicer Python Console. I tested it on Ubuntu 20.04, Slicer 5.4.0 r31938 / 311cb26, and VS code 1.82.1.

Thanks on advance

It seems that debugpy developers messed up something last week or the week before, so there were some broken versions. I’ve just tested the debugger in VS Code and everything works (with debugpy latest version 1.8.0).

You already have debugpy installed in Slicer’s Python environment, so if you want to get the latest version then you can run pip_install('debugpy --upgrade') in the Slicer Python console.
