XML : Mule the namespace on the "definitions" element, is not a valid SOAP version

I have a Mule flow that uses the Web Service Consumer to call a SOAP Web Service.

I have checked that the XML that I give to the Web Service Consumer for the request is fine. The XML works fine for instance if I test it in SoapUI.

The same produced XML throws the following error when using the Web Service Consumer component:

  ERROR 2016-01-26 13:53:00,194 [[api-gateway].http-lc-0.0.0.0-8081.worker.01] org.mule.exception.CatchMessagingExceptionStrategy:   ********************************************************************************  Message               : "http://schemas.xmlsoap.org/wsdl/", the namespace on the "definitions" element, is not a valid SOAP version.. Message payload is of type: NullPayload  Type                  : org.mule.module.ws.consumer.SoapFaultException    

This seems to be like the Web Service Consumer does not detect the Soap Version correctly.
