      Thanks for the additional information. I don't see anything clearly wrong in your code, and since it only happens with files from Google Drive, it sounds like there's something unique to how the files are returned from Google Drive.

       

      Can you try using Chrome Remote Debugging to see if you can get a more specific error?
