com.pega.pegarules.pub.clipboard.InvalidReferenceException: The reference .pxFlow().pyIssuedFromStage is not valid.

Hi, 

I've been seeing this error, and would like some assistance in understanding this.

Based off the first line, is it likely that somehow a subscript is passed as a param into pxFlow somewhere?

@Renard

It's the step 4 of startFlow activity that is throwing this issue.

From the stack trace it looks like SLA agent is processing an event (Goal/Deadline/Late) which in turn invoking a new flow without flow name parameter passed.

Can you check your code (SLA rule) if it is possible in some circumstance system tries to invoke a flow without a name?

Thanks
