title: Graphene Django returning null values
body: <p>When using the following schema I keep getting null values when querying for products. From my understanding of the documentation, it should return an array with 2 objects containing id and name. Can anyone help me to understand why the following code does not work?</p>
  
  <pre><code>import graphene
  
  class Product(graphene.ObjectType):
      id = graphene.Int()
      name = graphene.String()
  
  
  class Query(graphene.ObjectType):
      products = graphene.List(Product)
  
      def resolve_products(self, info, **kwargs):
          return [{
              "name": "TEST", "id": 1
          }, {
              "name": "TEST2", "id": 2
          }]
  
  schema = graphene.Schema(query=Query)
  </code></pre>
