I start cases via a trigger element with a delay (blocking period) and some parameters. In another prozess I query this delayed tasks an want to retrieve the parameters with the getStartProcessData() method like with other running tasks. But the method here returns always null. Is there a way to get the input parameter of a delayed started case?
