You have set it to a class method (more precisely, an
"unbound method instance"). To help prevent trivial
programming errors, they check that an object of the
correct type is passed in.

You get the underlying function through the "im_func" pseudo
attribute. Thus, you use

   HTTPResponse.unauthorized = PortalUserFolder.unauthorized.im_func
