Description

handle_user_exception.__doc__

This method is called whenever an exception occurs that
        should be handled. A special case is :class:`~werkzeug
        .exceptions.HTTPException` which is forwarded to the
        :meth:`handle_http_exception` method. This function will either
        return a response value or reraise the exception with the same
        traceback.

        .. versionchanged:: 1.0
            Key errors raised from request data like ``form`` show the
            bad key in debug mode rather than a generic bad request
            message.
