storage: 404 not found after upload

Hi, right after uploading a file I need to get it back and Storage returns a 404:

fs.createReadStream('/local/photo.jpg').pipe(bucket.file('photo.jpg').createWriteStream().on('finish', function(){
  console.log('write finished');

  bucket.file('photo.jpg').createReadStream().pipe(fs.createWriteStream('/downloaded.jpg'));
}));

Is there a better callback to know when a file is fully uploaded to Storage please ?
Thanks

Thanks to @ngrilly the event is not "finish" but "complete":

fs.createReadStream('/local/photo.jpg').pipe(bucket.file('photo.jpg').createWriteStream().on('complete', function(){
  console.log('write finished');

  bucket.file('photo.jpg').createReadStream().pipe(fs.createWriteStream('/downloaded.jpg'));
}));
