I am on Sharepoint 2010 and trying to complete a flexi task via web service. My configurations are as follows, but I'm unable to get it to run without error. What am I doing wrong?
Error from ULS log:
Nintex.Workflow.NWActionExecutionException: Error returned from server: <soap:Fault xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>soap:Client</faultcode><faultstring>Server was unable to read request. ---> There is an error in XML document (1, 339). ---> Input string was not in a correct format.</faultstring><detail /></soap:Fault> ---> System.Net.WebException: The remote server returned an error: (500) Internal Server Error.
