I keep on getting this error for our process builder whenever I add the variable [Case].Owner:Queue.DeveloperName into the Criteria.
Basically, the PB will check if the Owner of the Case does not belong to a Queue, will not proceed to perform any actions. If it does belong to a Queue, then it will do some actions.
However, when I try to create manually a Case, then I get this error:
Error element myDecision (FlowDecision). The flow failed to access the value for myVariable_current.Owner:Queue.DeveloperName because it hasn't been set or assigned.
The criteria of the PB is just this:
Operator: Is null
Any help is much appreciated. I've been stuck on this issue since yesterday.
