| ERROR | cannot propagate object type payloads that have a REF attribute |
| CAUSE | An ADD_SUBSCRIBER or ENQUEUE procedure with a non-NULL address field in the agent type was issued on a queue whose payload has a REF attribute. Propagation of object type payloads that have a REF attribute currently is not supported. |
| ACTION | Specify an agent with a NULL address field so that the agent can dequeue from the same queue. Or, change the object type definition to one that does not use REF attributes. |
