So everthing wihtin the <ns1:xml> is a string, starting with <![CDATA...! I have run this SOAP connect several times and PEGA is doing strange parsing. Pega replace all "<" with "<" which i can recognize in the log (<![CDATA...) and the corresponding Service can not handle this!
I am calling the Connect SOAP in an activity. Steps 2-5 are only test purpose!
