saveWithAttachment is resolving to failure callback

[jgadbois]

I'm calling model.saveWithAttachment which is returning a 200 with a JSON response, but it's going to the failure callback.

With .save it goes to the success callback.

Any ideas why the discrepancy?

// later on i save the model like this - second call back is being hit.
this.get('model').saveWithAttachment().then(function(result) {
   controller.set('saving', false);
   controller.transitionToRoute('dashboard.trainer.groups')
