Enable role fails with permission error

With version 0.0.8 of the module, i am trying to activate a role using this syntax:
Enable-JAzRole -RoleName 'Contributor -> Scope (Guid)'

But that fails with the following error message:
_Enable-JAzRole: The requestor "id" does not have permissions for this request. Please use $filter=asTarget() to filter on the requestor's assignments._

Have tried using -Verbose flag, but that did not bring any additional info.

Start by reproducing Enable-JAzRole -RoleName with the reported Contributor scope and inspect its verbose request construction. Compare the request with the service error's required $filter=asTarget() behavior; done means an authorized role activation succeeds without the permission error.
