Hello,
While trying to invoke Connect SOAP, getting error " com.pega.apache.axis2.AxisFault: The input stream for an incoming message is null."
I am using PEGA 7.1.9
The InvokeAxis2 activity step 15 is failing and causing this error.Can any one tell me what might be the error and how to rectify it?
