Debugger is attached but can't stop on breakpoints

[SanzioCaroli]

OS: Windows 10

Add-on Version: 2.2.0

Blender Version: 3.2.1

VS Code Version: 1.69.2

VS Code Python Extension Version: v2022.10.1

• debugpy version: 1.6.2

Paths listed by where python or the corresponding command:
where python
C:\Program Files\Blender Foundation\Blender 3.2\3.2\python\bin\python.exe
C:\Program Files\FreeCAD 0.18\bin\python.exe
C:\Users\carolisa\AppData\Local\Programs\Python\Python310\python.exe

Does VS Code / Visual Studio connect to the troubleshooting script?
Yes

Python path/interpreter detected/selected by VS Code/Visual Studio:
C:\Users\carolisa\AppData\Local\Programs\Python\Python310\python.exe

Blender and VSCode connect succesfully ( see picture attached ).
But if I set a breakpoint on VsCode (on the print("test") statement) and I run the script with Alt-P on Blender, the breakpoint is ignored.

Maybe failed to upload in the message above...

I found that if I move my python source code file on c:, everything works.
It seems the debugger can't find the source code and looks on c:.
How to specify the right path?

Where was the script located and where did you move it to that it now works?

Also running scripts from Blender can be a problem. I remember some potential workarounds were discussed in #4, but I never got around to investigating.

Not certain I was hitting the same issue, but after considerable head-scratching as to why the debugger couldn't match the source file I placed breakpoints in with the source of the addon, I decided to dig around VSCode for source path search settings (similar to Visual Studio) and found that you can specify the search path directly (vscode edit->preferences->settings then search for "debug path") (the add-on I wanted to debug was in c:\temp\addons...)

Restarted blender, reconnected the debugger and it worked as expected.

What solved the issue for me was to change the auto-generated VSCode launch.json file. Specifically, "pathMappings.remoteRoot" should be set to "${workspaceFolder}" instead of the default ".".
here is my complete launch.json:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Remote Attach",
            "type": "python",
            "request": "attach",
            "connect": {
                "host": "localhost",
                "port": 5678
            },
            "pathMappings": [
                {
                    "localRoot": "${workspaceFolder}",
                    "remoteRoot": "${workspaceFolder}" // I think this did the trick
                }
            ],
            "justMyCode": false
        }
    ]
}

Change removeRoot to ${workspaceFolder} works for me! Thank you! 😸

Had the same issue.
The solution mentioned by DaseinPhaos worked for me too.

I will see if I can reproduce this and add it to the docs if so. Also @rlneumiller that is from a separate VS Code extension and not an internal setting of VS Code.

I have the same problem and unfortunately, setting the path as @DaseinPhaos suggested did not work for me.
Blender 3.65 and VSCode 1.88.1 with Python 3.10.11.
Is anyone else still having problems with Breakpoints not triggering?
