I am using web service consumer in Mule4 and after configuration and deployed the application and triggered the target ARIBA SOAP service in logs I see below error:
org.apache.cxf.binding.soap.SoapFault: Error reading XMLStreamReader: Undeclared namespace prefix "soapenv" at [row,col {unknown-source}]: [1,14]
When I explored the error I see it is an issue at target system end :], please let me know whether it is end system thrown error or any pointers on what would cause this issue.
