Cannot debug poetry error: TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType

[John15321]

Issue Type: Bug

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: Version: 1.69.1
• OS Version: macOS 12.4 21F79 arm64

Steps to Reproduce:

1. Install poetry https://python-poetry.org/docs/
2. Clone the poetry repository
3. Create a poetry shell by running poetry shell this will create a poetry managed venv (the same issue happens with a normal venv)
4. Install poetry locally poetry install
5. Create a debug configuration like this:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "poetry help",
            "type": "python",
            "request": "launch",
            "module": "poetry",
            "args": [
                "-vvv",
                "--help"
            ],
        },
}

6. Run the configuration
7. This is the error Im getting (I also tried it in a debian docker container):

$  cd /Users/john/Documents/Programming/poetry ; /usr/bin/env /Users/john/Library/Caches/pypoetry/virtualenvs/poetry-WR0MsEPb-py3.9/bin/python /Users/john/.vscode/extensions/ms-python.python-2022.10.0/pythonFiles/lib/python/debugpy/adapter/../../debugpy/launcher 56594 -- -m poetry -vvv --help

TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType 

For some reason Pycharm runs an equivalent configuration without a problem:

1. Open the file at your computer:

/Users/john/.vscode/extensions/ms-python.python-2022.10.0/pythonFiles/lib/python/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_process_net_command_json.py

2. Change lines 443 -> 446 to be:

               if f:  # argv[0] could be None (https://github.com/microsoft/debugpy/issues/987)
                    if os.path.isdir(f):
                        watch_dirs.append(f)
                    else:
                        watch_dirs.append(os.path.dirname(f))

Saw this issue today, except on Windows the underlying call is to _isdir instead of stat:

Thanks @fabioz for the patch.
