title: cannot read property of undefined - but property exists
body: <p><code>console.log(result.data[0]);</code></p>
  
  <p>returns:</p>
  
  <pre><code>{ name: 'page_stories',
    period: 'day',
    values: 
    [ { value: 114, end_time: '2016-07-31T07:00:00+0000' },
      { value: 68, end_time: '2016-08-01T07:00:00+0000' },
      { value: 134, end_time: '2016-08-02T07:00:00+0000' } ],
    title: 'Daily Page Stories',
    description: 'Daily: The number of stories created about your Page. (Total Count)',
    id: '462582393917692/insights/page_stories/day' }
  </code></pre>
  
  <p>but for some reason <code>var name = result.data[0].name;</code> is returning:</p>
  
  <p><code>TypeError: Cannot read property 'name' of undefined</code></p>
  
  <p>I can't for the life of me figure out why. the 'name' property clearly exists as does the result.data[0] object. Any help would be fantastic.</p>
  
  <p>edit: found out that the data format wasn't uniform for every single request (just most!). Thanks for the responses. I should've made it clear that I was feeding batch requests through this code too.</p>
