Hi, I am having an issue with mypy throwing an error

Signature of "authenticator" incompatible with supertype "RESTStream"

when using

@cached

from memoization on the authenticator method in a stream. The tap works otherwise but mypy does not like it. Has anyone run into this before? I don’t get a mypy error when

@cached

is not used. I am following the code sample here https://sdk.meltano.com/en/latest/code_samples.html#make-a-stream-reuse-the-same-authenticator-instance-for-all-requests

Hi Robby. What version of mypy are running on your tap?

mypy 1.1.1 I did find a temporary fix by changing

@cached

to

@cached  # type: ignore

Yup, and from experience it’s even better to specify the ignored error:

# type: ignore[override]
