Take a look at root.py lines 47-58. There is set some error handlers
according to error code. Probably, the default error handler for 403 is
a HTML page set by cherrypy.
You will need to add a specify 403 error handler for your matters.

InvalidOperation will raise a 500 error code. The other message is
usually used when an exception was not catch by anything. In that case,
you should see an traceback in the logs reporting the original exception.
