"Backend Error" when setting file ACL

Trying to set ACL after uploading and consistently getting a "Backend Error" when trying to set ACL. File uploads fine each time.

var image = myBucket.file('foo.jpg');
var imageWriteStream = image.createWriteStream({ contentType: 'image/jpeg' });

imageWriteStream.on('complete', function() {
  // Set ACL
  image.acl.add({
    scope: 'allUsers',
    role:  gcloud.storage.acl.READER_ROLE
  }, function(err) {
    // FAILING HERE
    console.log(err);
  });
});

my Stream.pipe(imageWriteStream);

Thanks for reporting, I'll check it out!

Just confirming, are you on gcloud version 0.18?

Sorry about that. No, I'm on v0.15.0. The version installed through NPM. Is there an ETA of when v0.18 will be in NPM?

It's actually out now. What value do you have in your package.json?

My bad. I must have previously installed it so it was stuck on v0.15. I updated and the problem persists.

Is the messaging still Backend error? We actually changed how errors are patched from the API - maybe it's more helpful this time around. At the very least, it should be "Error during request".

Oops, I just noticed we have incorrect docs. The parameter to use is actually entity instead of scope. Not sure that will be the fix here, but let's hope 🎌
