it's not found http response code(400 401 403 500), just have http response code 200. Why???

If add RemoteServiceAttribute, it's may be work. why?
But the class BookAppService was already implement IRemoteService... it's make me confused.
I think the class it's implement IRemoteService should have the RemoteServiceApiDescription as default
