Push SOAP request to PI using wsnavigator

Hi Experts,

"Call failed: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.lang.NullPointerException: while trying to invoke the method com.sap.engine.interfaces.messaging.api.Payload.getInputStream() of a null object returned from com.sap.aii.adapter.xi.ms.XIMessage.getMainPayload() ".

The error in wsnavigator is as follows:

Thanks,

Nithin.
