加载路线时出现Ember错误

Question

我有一个Group模型，它将一个json feed拉入一个数组，然后它假设将它呈现给组模板。

我的模型看起来像这样：

Mdm.Group = Ember.Object.extend(); // Creating new model class

Mdm.Group.reopenClass({
  all: function() {
    return $.getJSON("http://localhost:3000/1/organizations/1/groups?format=jsonp&callback=?").then(function(response) {
        var groups = [];

        response.groups.forEach( function (group) {
            groups.push(Mdm.Group.create(group));
        });
        return groups;
    });
  }
});

我的GroupsRoute：

Mdm.GroupsRoute = Ember.Route.extend({
    model: function() {
        return Mdm.Group.all();
    }
});

应用程序正在检索json。检查器中的网络选项卡可以完美地加载每条记录，而不是将其吐出来。

在控制台中，我收到以下错误：

Uncaught SyntaxError: Unexpected token : groups:1
  Error while loading route: 
  Object {readyState: 4, getResponseHeader: function, getAllResponseHeaders: function, setRequestHeader: function, overrideMimeType: function…}

我知道大部分内容毫无意义，但如果有人见过这个，我会感激任何反馈。
