How to use pyright with venv created by pdm?

[malik-n]

Pyright works correctly when using it in a PDM script by defining the script in the pyproject.toml and setting pyright as dev dependency

[dependency-groups]
dev = [
    "pyright",
]

[tool.pdm.scripts]
type-check = "pyright src"

When using Pyright by itself or as language server for Helix the import statements cause errors. (reportMissingImports)

Trying to fix it in the pyproject.toml like this did not work:

[tool.pyright]
venvPath = ".venv"
useLibraryCodeForTypes = true

The venv created by PDM is in the root of the project with the path .venv and the following directories and file inside: bin include lib pyvenv.cfg

How do I setup the configuration correctly?

Propably related to #2767 and pdm#804

Converting to a discussion since this is a question, not a bug report.

Found the solution here: https://notes.billmill.org/programming/python/pyright_use_virtualenv.html

[tool.pyright]
venvPath='.'
venv=".venv"
exclude=['.venv']
