How to return Stream a Soap response

Primary tabs

I am trying to return a stream soap response using web services I can call my web service supply it with a xml string which works fine . I then work on that XML and try to return  a Stream but all works in the production when my service receives the stream after I get the error  as if its trying to copy stream to a variable and I am confused as to where that operation happens.

The errors I am getting 
ERROR <Ens>ErrException: <METHOD DOES NOT EXIST>zCopyFrom+28^%Stream.TmpCharacter.1 *Rewind

and here is the stack trace in case I am missing something

 the service code is as follows please note the method being called by the web method is just a switch statement which directs to the intended method process thanks in advance



Method TestTwo(pInput As %String) As %String [ WebMethod ]
    set tSC=..ProcessInput(pInput,.oRes,"TestTwo")
    do:$$$ISERR(tSC) ..ReturnMethodStatusFault(tSC)
    quit oRes
Method processTestTwo(pInput As %String) As %String
   #;the message class for the file meta data
  #dim oMREQ as PDFRendering.Message.FOPPDFRenderRequestMREQ=##class(PDFRendering.Message.FOPPDFRenderRequestMREQ).%New()
    If (pInput'="")
        do oMREQ.Source.Write(pInput)
        set tSC=..SendRequestSync(..TargetConfigNames,oMREQ,.response)
        if $$$ISERR(tSC) do ..ReturnMethodStatusFault(tSC)
        //use info from Ensemble response to create SOAP response
         set soapresponse=##class(PDFRendering.Message.FOPPDFRenderRequestMRES).%New()
         set soapresponse.Document=response
         set incoming=soapresponse.Document_""
         set incoming="Input empty"
    quit incoming
