Custom file pass through Operation writing out unreadable pdf files

I have a service that takes a file and pass it through to the production .While I am passing the file through I get the file stream and set it to a variable within my message and the variable is of type %Ens.StreamContainer. But after all processing and I need to write out my file to a pdf format The file gets written but is a corrupt file since I can not read it I have tried this with asimple pass through everything is fine .But here I do not know what I am doing wrong here is the operation code

 set pInput=pRequest.FileStream
     ;the variable to hold the status for the method
 #dim status as %Status=$$$OK
 ;clear the pResponse
  kill pResponse
     set pResponse=$$$NULLOREF
 ;set the file name to the sequence number
  set ..Filename=pRequest.NewFileName
 
  ;the filepath set on the settings of this OPERATION
   set origDirectory = ..Adapter.FilePath
  ;the file directory to drop the file
  set ..Adapter.FilePath = ..Adapter.FilePath_"\"_..StubDirectory
  
 ;start writing out file data to the file in filename
;this bit works fine
    set:$$$ISOK(status) status= ..Adapter.PutLine(..Filename_"."_..stubExtension,
  $CHAR(34)_ pRequest.ClientID_$CHAR(34)_$CHAR(44)_$CHAR(34)_pRequest.UserId_$CHAR(34)_$CHAR(44)_$CHAR(34)_
  pRequest.DocumentType _$CHAR(34)_$CHAR(44)_$CHAR(34)_pRequest.Title_$CHAR(34)_$CHAR(44)_$CHAR(34)_pRequest.Description_$CHAR(34)_$CHAR(44)_$CHAR(34)_pRequest.Author _$CHAR(34)_$CHAR(44)_$CHAR(34)_pRequest.DocumentDate_$CHAR(34)_$CHAR(44)_$CHAR(34)_pRequest.FinalRevision_$CHAR(34))
 
 if ($$$ISOK(status))
 {
  ;set back to the operation settings
  set ..Adapter.FilePath = origDirectory
    ;set the file name  to write out to
  set ..Filename=pRequest.NewFileName_"."_..DocExtension
  ;set the filepath on the production settings to this variable
  set origDirectory = ..Adapter.FilePath
  ;set the new filepath
  set ..Adapter.FilePath = ..Adapter.FilePath_"\"_..DocumentDirectory
     
 
  //here I turn to write out but file is corrupt
  
   Quit:'$IsObject(pInput.Stream) $$$ERROR($$$EnsErrGeneral,"No Stream contained in StreamContainer Request")
 Set tFilename=..Adapter.CreateTimestamp(##class(%File).GetFilename(pInput.OriginalFilename),..Filename)
 Set status=..Adapter.PutStream(..Filename, pInput.Stream)
 Do pInput.%Save() ; re-save in case PutStream() optimization changed the Stream filename
 
 
 
 
   set ..Adapter.FilePath = origDirectory
  
   if ($$$ISOK(status))
 {
  set pResponse=##class(BSMHFT.DocumentUpload.GenericRESP).%New()
  set pResponse.Process="RiOFileOPRN_files Written to their respective directories"
  set pResponse.Status=status
  set status=pResponse.%Save()
 }
  
 }
 
 return status
