[vikigenius]

Thank you for the bug report

Bug description

False positive in lsp pyright doesn't match command line behavior

Steps to reproduce

from typing import Literal


class LWPRSService(object):
    """Lightweight PRS Service."""

    def __init__(self, env: Literal["prod", "dev", "stg"] = "stg", country: Literal["us", "ca"] = "us") -> None:
        super().__init__()

  ]
}

Expected behavior

When I run the file through the pyright CLI no diagnostics are produced.

Setting reportUnusedVarialbe = false in pyproject.toml has no effect. And it should not be needed in the first place.

Which Language Server did you use?

lsp-pyright

Anything else?

I do see a bunch of messages Invalid face reference: lsp-flycheck-info-unnecessary [79 times]. Don't know if that is related.
