      Hello mongoDB Team
      I have an issue with golang driver and mongoDB. I want to download files from gridfs with downloadStream. Upload wasn't a problem,but if I try to download as you see in the code above, i will get the result like below .But it wasn't successful, because my log.Printf shows me nil.

      Write file to DB was succesful, File size: 3, FileID: [93 82 190 120 106 41 138 138 124 134 194 179]Download file from DB was succesful, File size: 0 Content: []
