This is my problem with placement rest api.(Token and endpoint were OK)

        {"errors": [{"status": 403,

                         "title": "Forbidden",

                         "detail": "Access was denied to this resource.\n\n Policy does not allow placement:resource_providers:list to be performed.  ",

                         "request_id": "req-5b409f22-7741-4948-be6f-ea28c2896a3f"

                        }]}
