Show unknown fields by default #23
Description
When receiving a protobuf message of the wrong type (or specifying the wrong expected response type) often times no fields can be properly matched and the protobuf payload will be interpreted as empty. While we cannot guarantee to get an error in such a case, we can at least still show unknown fields which were present in the payload - and hence, make it easier for the user to detect, when they specified the wrong response type.
