Thanks for your gist, it helps a lot. But I have tried it an realized there is one line missing: return this; Without that line it is impossible for me to use properties from original js error object (message and so on)

import Ember from 'ember';

let CustomError = function (errors, message = 'This error is result of my custom logic.') {
  Ember.Error.call(this, message);

  this.errors = errors || [
    {
      title: 'This is custom error.',
      detail: message
    }
  ];

  return this;
}

CustomError.prototype = Object.create(Ember.Error.prototype);

export default CustomError;
