Task completion criteria for journeys task

Summary: Task completion criteria for journeys task

Content (please ensure you mask any confidential information): Hi all, I have configured task completion criteria for one task in a journey.

I have entered that if the DOB is null, then system should throw an error.

However, when I tested it, it didn't work as expected and I was able to mark the task as completed.

I have attached a document with screenshots. Would appreciate if someone could please help on this.
