1) The error is given for the line

using (MemoryStream memoryStream = new MemoryStream(byteArray)) {
  memoryStream.Write(byteArray, 0, byteArray.Length);
  memoryStream.Position = 0;
   using (GZipInputStream gzipInputStream = new GZipInputStream(memoryStream)) {
      using (StreamReader streamReader = new StreamReader(gzipInputStream)) {
        return streamReader.ReadToEnd();
      }
   }
 }

2) The error is given for the line
