I'm not convinced that this is a pytest bug; looking at the source location and trying to reproduce it seems fine? I'd guess that some other code is patching something in a weird way.

[kloczek]

Which one code and in what "weird way"?

[RonnyPfannschmidt]

@Zac-HD im under the impression that the warning comes from fixture parsing a magic object in that library

[Zac-HD]

Closing because we don't have the needed information to resolve this, happy to reopen if that changes 😕
