How to use the js-data.DSUtils function in js-data

container.register('DS', function (Promise, container, sqlAdapter, messageService) {
  var JSData = require('js-data');
  JSData.DSUtils.Promise = Promise;
  var store = new JSData.DS({
    cacheResponse: false,
    bypassCache: true,

    // Important: If your relationships stop working, you might
    // have deleted this.
    linkRelations: false,

    // Because
    upsert: false,

    // Don't really need this stuff on the server, so let's improve
    // performance and disable these features
    notify: false,
    keepChangeHistory: false,
    resetHistoryOnInject: false,
