Hi,
We have 4 organisation units. Im trying to download queue items from all four organisation unit using “get queue items” activity but it is recognizing queue names from only one organisation unit. for rest all queues from different units it is throwing exception saying “An invalid result was encountered for parameter queue name”. Can someone help me with this issue.

Thanks in advance!!!

I am trying to get queue items from orchestrator to delete before actual queue items are loaded. But I am getting this error. Get queue items: An invalid result was encountered for parameter QueueName.
Can anyone help me.
