Resolved above issue by setting SOAPAction header with the appropriate action which is found using the WSDL and changing the content-type from application/xml to text/xml as I was using an HTTP client to send the SOAP request.

Sample request:

POST /services/HandlerProxy HTTP/1.1
content-type: text/xml
SOAPAction: urn:mediate
host: example.com:9080
user-agent: myClient
connection: keep-alive
content-length: 1251

You will have to set the right soapAction, currently your action is NULL. Basically this error tells you that the combination of endpoint and action is not known on the ESB.

If you checkout the WSDL of the echo service you will see there are multiple operations possible. For example "urn:echoInt"
