#20819 pyright not able to discover pyproject.toml in source root Issue created by bugzpodder Describe the bug Repo: https://github.com/bugzpodder/example-python I have a source root in /helloworld/ and a pyproject.toml there. (I also tested without source roots, and pants + pyright worked with no issues) When I run pyright in /helloworld/ without pants, it works fine (my current workflow) When I run

pants check ::

in root dir, it does not work because it can't find pyproject.toml This is different from pants' ruff integration where it is able to work with the pyproject.toml with no issues.

If you check the sandbox, you'll see it added pyrightconfig.json but it did not pick up pyproject.toml in helloworld

Pants version 2.20 OS MacOS locally, the repo above is from a VSCode sandbox (linux) Additional info for running pyright outside of pants, it only recognizes the pyproject.toml in cwd (the place you run it in). pantsbuild/pants
