I also had the same issue. Had to assign roles manually to different users.
openstack role add --project service --user magnum admin
openstack role add --project service --user heat admin
openstack role add --domain heat --user trustee_domain_admin admin
openstack role add --domain heat --user heat_domain_admin admin
I gave admin roles to different users to fix this.
