Error while invoking Web Service Requests with message - java.lang.IllegalArgumentException: argument type mismatch

Issue

• We are trying to invoke the web service request using CXF endpoint. But during the time of invocation it is failing and throwing the error as - "Interceptor for {http://xyz.abc.com/}SOMEAPIService#{http://xyz.abc.com/}getSomeMethod has thrown exception, unwinding now
  org.apache.cxf.interceptor.Fault".
• With SoapUI there is no problem, and request is sent successfully.
• On the fuse Console the stack trace is as shown below.
