HANA Academy - Native Dev Video: Error Creating Role

I'm following along with the "Create Roles" video in the Native Development Workshop.

After creating the .xsprivileges artifact with the depicted content, the .hdbrole file commits fine, but errors out when trying to activate...

ERROR      PBDemos/MyOData02/data/pbdemoUser.hdbrole

           insufficient privilege: Not authorized at ptime/query/checker/query_check.cc:2547

ERROR      PBDemos/MyOData02/data/pbdemoUser.hdbrole

           A transaction rollback may have left the object in an inconsistent state.

ERROR                 exception 40183:
