The error handler needs to return a response, since the response headers need to be updated with the problem HTTP content type. This does mean, though, that to support a symmetry-of-results between a function that returns successfully (e.g., login) and the handler that is called in the event of the function raising an exception, each must return the same data type. In other words, (login …) cannot be wrapped in a response, since – when it fails – its error handler will return one. This would result in a regular response upon success and a nested (improper) response upon failure.
