javascript - Ember-data cannot read property 'length' of undefined -

i'm trying data api server ember-data ,i added ember-data ember starter-kit.

getting

app = ember.application.create();  app.router.map(function() {   // put routes here });  app.applicationadapter = ds.restadapter.extend({     namespace: 'emberjs/ember.js',     host     : 'https://api.github.com/repos' });  app.store = ds.store.extend({     adapter: 'app.applicationadapter' });  app.indexroute = ember.route.extend({   model: function() {     return this.store.find('pull');   } });  app.pull = ds.model.extend({     url : ds.attr(),     title  : ds.attr(),     body  : ds.attr() }); 

giving same error every request. try github, gives same error.

api connected: github api

error while processing route: index cannot read property 'length' of undefined typeerror: cannot read property 'length' of undefined

ember expects pluralised root object when returning multiple results, in case pulls, i.e

{     "pulls": [...] } 

as you're working api don't control you'll need change data embers expected format modified serializer so:

/app/serializers/pull.js

import ds "ember-data";  export default ds.restserializer.extend({     normalizepayload: function(payload) {         if(array.isarray(payload)) {             return {"pulls": payload };         }         return payload;     } });
