Error: Bad Task Sequence reference in finish task sequence activity

My tokens and associated items will move appropriately until the end of the IQ_Visual_Waf process flow activity. After completion, the tokens stay in the Finish Task Sequence activity and I get the error exception: Error: Bad Task Sequence reference in finish task sequence activity IQ_Visual_Waf/Finish TS in process flow "ProcessFlow".


Additionally, after 4 tokens build up in the Finish TS step, no more tokens move into the IQ_Visual_Waf process flow and the operator stops collecting boxes from the IncomingWafers rack.

The issue is that you told the processor to use "QualityTech" as the operator for setup and for processing, and you told the processor that it could preempt and abort active tasks on the operator:

This is aborting the QualityTech's Task Sequence.

You already have the operator acquired and at the machine via process flow, so you don't need the "Use Operator" on the actual processor.
