Hello Ronald! I started over with a new process. One thing I observed is that I let my DecisionHandler return task names but instead the transition's name between the task and the next task was needed. So there might be some other mistakes like this. If I encounter the same problem again even with paying attention to all these aspects I am going to repost.
