Ember-data-url-templates - shapshot.belongsTo is not a function


I’m trying to use ember-data-url-templates add-on and getting the below error in the adapter:

# adapters/shop_language.js

import ApplicationAdapter from './application';
import UrlTemplates from "ember-data-url-templates";

export default ApplicationAdapter.extend(UrlTemplates, {
  findAllUrlTemplate: '/shops/{shopId}/languages',
  createRecordUrlTemplate: '/shops/{shopId}/languages',

  urlSegments: {
    shopId: function(type, id, snapshot, query) {
      return snapshot.belongsTo('shop', { id: true });

In the shop-languages.js route handler:

# routes/shop_languages.js
import Route from '@ember/routing/route';
import AuthenticatedRouteMixin from 'ember-simple-auth/mixins/authenticated-route-mixin';
import RSVP from 'rsvp';
import { inject as service } from '@ember/service';

export default Route.extend(AuthenticatedRouteMixin, {
  currentShop: service('current-shop'),

  model() {
    return RSVP.hash({
          shopLanguages: this.store.findAll('shop-language', { shop_id: this.get('currentShop.shop').get('id')}),
          languages: this.store.findAll('language')

When I try to access the above route, I get the below error:

Uncaught TypeError: snapshot.belongsTo is not a function
    at Class.shopId (shop-language.js:13)
    at url-templates.js:39
    at subFunction (uri-templates.js:103)

Do I use this add-on in a wrong way ? Should I import in some way the snapshot-api ? Thank you.
