Hi @chbndrhnns,

Thanks for the PR.
The response validation is not always hit though. Eg. if it is deactivated, or if there is no validator for the returned content type. We should probably implement this in the response decorator.

Please take a look at the linked issue. My fix only applies when validate_responses is True. Let me know if you still want to move the logic.

The root cause is indeed in the response decorator, as HTTPStatus members are of type IntEnum so they pass the isinstance(..., int) check. We can check explicitly for this first, or we should also be able to resolve it by simply wrapping the status code in another int() call here, so:

connexion/connexion/decorators/response.py

Line 141 in 823fa6c

status_code = status_code_or_headers

becomes

status_code = int(status_code_or_headers)

Edit: seems like the second if-branch should also catch it, so swapping the order could also work? Not sure in which cases that branch is entered :)

I moved the change to the proposed location.
