However, in the middle of the workflow, there would be an actor that outputs an array with arbitrary length. I want to process each element of the array using another actor all in the same iteration, and it seems the easiest way to do that is by using the ArrayToSequence actor. However, the actor requires arrayLength parameter to be set prior to running the workflow.
