[The-Compiler]

According to the stacktrace, this is coming from pytest-asyncio - most likely because you set asyncio_mode to an incorrect value. Not a pytest issue in either case.

[The-Compiler]

I opened a PR against pytest-asyncio to improve the error message: pytest-dev/pytest-asyncio#557

[The-Compiler]

The PR got merged, so with the next pytest-asyncio release, this will now print:

$ pytest -o asyncio_mode=True
