Handling Errors with RESTSerializer - ember.js

Question

Using ember and ember-data 2.6 versions, I'm trying to get error handling working but running into issues. I'm using the RESTSerializer and I'm sending the following payload to my server:
{
"brand": {
"name": null,
"description": null,
}
}]
Since name cannot be null, this is what I'm sending back as my response:
{
"errors": [{
"code": null,
"detail": "may not be null",
"status": null,
"title": null,
"source": {
"pointer": "brand/name",
"parameter": null
}
}]
}
In my route, I am doing the following in the save promise on failure:
console.log(savedBrand.get('isValid')); // logs false
console.log(savedBrand.get('errors').toArray()); // logs [ ]
There doesn't seem to be a lot of detailed documentation on how this all works so I'm using this article as a starting point. I'm unsure as to why toArray() returns an empty array instead of my error that I'm returning in the JSON.

Answer 1

even though I'm not passing in the data per the json-api, the pointer still had to be set as if I were:
{
"errors": [{
"code": null,
"detail": "may not be null",
"status": null,
"title": null,
"source": {
"pointer": "/data/attributes/name",
"parameter": null
}
}]
}
