Not executing payload process

After receiving a EDIINT message, the MDN being sent back is failing. Error ‘ [ISC.0064.9322] expecting : (58) got
(13) context: HTTP/1.1 500 Internal server error’
In the second attempt the MDN is being sent correctly. However the payload is not being executed via the processing rule and therefore the message remains in TN.

Is there a way to enforce the payload to be processed or better prevent this error. The processing rule has synchronous processing in the action tab / execute service.

Thanks Rob
