A WattEvaluationException was thrown by the XQL Query engine

Soap data we are sending is received by the client properly. We have a problem with response data. When we want to extract the data out of the SOAP message (soapResponseData) using pub.soap.utils:getBody or pub.soap.utils:getBodyEntries is giving error when soapResponseData is given as input.

Error:

<?xml version="1.0"?> [ISS.0088.9136] A WattEvaluationException was thrown by the XQL Query engine at com.wm.app.b2b.server.SOAPMessage.getBodyNode(SOAPMessage.java:264) at pub.soap.utils.getBody(utils.java:299) at sun.reflect.GeneratedMethodAccessor81.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at com.wm.app.b2b.server.JavaService.baseInvoke(JavaService.java:287) at com.wm.app.b2b.server.invoke.InvokeManager.process(InvokeManager.java:587) at com.wm.app.b2b.server.invoke.StatisticsProcessor.process(StatisticsProcessor.java:44) at
