My case is: trigger handlemktevent activity then offer promotions. it is ok for me. I put a handoff shape to my offer and call flow in it. Called flow includes utility shape which is referencing activity service call. You can see flow in a attached files. I also put data transform and logged datatransform. it works. but referenced activity is not called.Activity has log steps. When I test handoff shape test offer from here, referenced activity is called. I dont understand why it does not work when call it via handlemkt event.
