youtube.thumbnails.set isn't working

Hey. Trying to use youtube.thumbnails.set with videoId and media object properly set is giving me errors.

let req = Youtube.thumbnails.set(
  {
    videoId: video_id,
    media: {
      mimeType: "image/jpeg",
      body: "test.jpg"
    }
  },
  (err, thumbResponse) => {
    if (err) {
      console.log(err);
      process.exit(1);
    }
    console.log("thumbnail uploaded");
    console.log(thumbResponse);
  }
);

This results in Error: The provided image content is invalid.

Using a stream instead results in Error: write after end

The image I’m using is a typical 1280x720 image that I’ve tested by manually uploading to youtube fine. video_id is set to a video i own

At https://stackoverflow.com/questions/45535611/youtube-api-thumbnail-upload-isnt-working it was recommended I post here. full code sample at gist.github.com/2c2c/0736e87b6853b42828ad8480382ab427

@2c2c @sebseb7 @cot97 Try using a synchronous stream.

var upload_thumbnail = function(auth){
   var youtube = google.youtube('v3');
   youtube.thumbnails.set(
   {
     auth: auth,
     videoId: 'U49C3_DEWFM',
     media: {
       mimeType: 'image/jpeg',
       body: fs.readFileSync('youtube.jpg')
     },
   },
   (err, thumbResponse) => {
     if (err) {
       console.log("Error response");
       console.log(err);
       process.exit(1);
     }
     console.log("thumbnail uploaded");
     console.log(thumbResponse);
   }
 );
}
