Go error when reading BTFS

[zillerium]

I have a file in BTFS but when I try accessing via Go and just get headers and Nil. Code -

  //QmXEQPcQsPfGfFoannQG9jiH84P1BxwVAJ5sLapZDZfvWp
   sh := shell.NewShell("localhost:5001")

   for _, elem := range indArray {
         fmt.Printf("hash code  %s ", elem.Hash)
         cid, err := sh.Cat(elem.Hash)
         if err!=nil {
             fmt.Printf("\nerror: %s ", err)
         }

Output -

&{%!s(*http.Response=&{200 OK 200 HTTP/1.1 1 1 map[Access-Control-Expose-Headers:[X-Stream-Output, X-Chunked-Output, X-Content-Length] Vary:[Origin] Date:[Tue, 27 Aug 2019 07:30:00 GMT] X-Content-Length:[15355] X-Stream-Output:[1] Access-Control-Allow-Headers:[X-Stream-Output, X-Chunked-Output, X-Content-Length] Content-Type:[text/plain] Server:[go-ipfs/0.1.0]] 0xc420066e00 -1 [chunked] true false map[X-Stream-Error:[]] 0xc420276400 })}

There is a nil at the end of the output. The file is in BTFS and I have checked at the CLI. Is Go supported? I am using -
shell "github.com/ipfs/go-ipfs-api"
and
BTFS is running -
