Jupyter Notebook debugging not working on VS Code

Question

I'm trying to activate the debugging functions that are now available on VSCode for Jupyter Notebooks but I'm having some problems with that.

In my interface I can see the button to ' Run by Line ' next to every cell but when I click it nothing happens except the normal execution of the entire cell, but that mode is supposed to execute your cell line by line ... I've tried putting some breakpoints even I know it is not necessary in that mode but still nothing .

As you can see here the buttons for debugging are shown a few seconds after hitting the ' Run by Line ' button but they do nothing.

As a workaround to not being able to use that useful mode, I tried the standard debug mode of VSCode for Jupyter Notebooks which let you go breakpoint to breakpoint on your cell, the problem (I think it is) is that when I use that what VSCode does is open another tab with just the code of the cell I'm debugging in a temporary .py file, which is not the behaviour I would like to have, because I think it should do that on the Notebook tab itself without any new file...

Here I show you a screenshot of the temporary .py that it's created:

That's just the code of my notebook first cell!

Any help with this? I would like to solve both problems or at least one of them. I've checked the requisites for the debug modes and make sure I fullfill everyone of them but I'm not so used to use the debug functionalities of VSCode so maybe I'm skipping something.

This is a current bug. It was notified to the dev team here:

https://github.com/microsoft/vscode-jupyter/issues/8258

The bug is caused by vscode using a shortened username. In my case GUILLE~1 instead of Guillermo.

The current solution available is to create a new user in your computer with a maximum length of 8 characters.
