SOAP fault saying failed to location operation for the SOAP call

Hi,

I have a servicenow instance from client and I am making a SOAP request to insert an incident in their system. I have the endpoint, wsdl and auth parameters from the client. I am also setting the SOAP Action as per the WSDL but I still receive the fault in response.

The servicenow instance is wrapped in Oracle WSM server id.

endpoint: https://client-provided-server-id/sst/com.slma.ai01.Servicenowinstance.u_incident_ins

SOAP Action: http://www.service-now.com/u_incident_ins/insert

I am putting the basic auth details as given by the client 

and I finally make the call after connecting to the VPN.

I am trying to debug the issue, but not able to escape the error right now.

Thanks in advance
