Using `Ember.NAME_KEY` is deprecated, override `.toString` instead [deprecation id: ember-name-key-usage]

Problem

Since Ember 3.8 I see a deprecation warning:

Using `Ember.NAME_KEY` is deprecated, override `.toString` instead [deprecation id: ember-name-key-usage]

The warning comes from ember-cp-validations@3.1.4 that is in your dependencies.
From this line to be specific.

Solution

The deprecation was fixed in ember-cp-validations@v4.0.0-beta.6.

Please upgrade ember-cp-validations dependency.

Oh, I've just realized Ember.NAME_KEY was even removed in ember@3.12: https://github.com/emberjs/ember.js/releases/tag/v3.12.0

I didn't check it but probably this addon and ember-cp-validations < @v4.0.0-beta.6 don't work on 3.12.
