Currently pyright doesn't enforce the "send" type for generators when a yield from statement is used.

from typing import Generator


def func1() -> Generator[None, int, None]:
    x: int = yield


def func2() -> Generator[None, str, None]:
    yield from func1()

This is related to mypy issue python/mypy#14834.

This is addressed in pyright 1.1.323, which I just published. It will also be included in a future release of pylance.
