And the same if adding the invalid privilege to the exist privilege group:

>>> milvus_client.add_privileges_to_group("_1", ["binbin"])
RPC error: [add_privileges_to_group], <MilvusException: (code=65535, message=fail to execute task when operate privilege group)>, <Time:{'RPC start': '2024-11-20 15:54:54.021095', 'RPC error': '2024-11-20 15:54:54.153747'}>
