Hi Chris, with context it is the same problem. The method invocation error stays. We've tried everything (We think so...), but in this d**m request-chain nothing helped... In all situations the script worked fine without the request chain. If the service had output parameters I could guess i'm manipulating the wrong parameters, but there are no things returned to the chain. I think the only way for finding a solution is debugging from the core, but with that I have no idea how to start.
I'm totally confused... Best regards, Fabian.
