GOT IT!!!
Thank you very much Nick, I really appreciate your help. It feels damn good when it works!
My problem after getting the messages to debatch was my receive port. It was expecting the customerSchema type, not the debatched message type (customerDocument). So I changed my receive port to expect the customerDocument type and then I used a construct message shape to map the customerDocument message type to the customerSchema (basically the same except a different root node).
Well, again, i really appreciate the guidance. I think it’s time for a beer now!
