Think I need to configure the launch.json properly.
Currently I have:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Profil kleinanzeigen",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "args": ["--config=E:\\kleinanzeigen-bot\\myadds.yaml"]
        }
    ]
}

If I then run on "main.py" I get
ModuleNotFoundError: No module named 'kleinanzeigen_bot'

Hope anyone can help.

Thanks

Or maybe you could tell me how you develop? Different environment?

Thanks

I am using Eclipse with PyDev and debugging works just fine.

You can also use the command line debugger via pdm debug publish --config ..., for more infos how to use it check here https://realpython.com/python-debugging-pdb/ and here https://docs.python.org/3/library/pdb.html
