title: React Native: Facebook API /me/picture call returns FACEBOOK_NON_JSON_RESULT
body: <p>I am writing an android app and using <a href="https://github.com/facebook/react-native-fbsdk" rel="nofollow noreferrer">facebook/react-native-fbsdk</a> to retrieve user's facebook profile picture. The call returns this:</p>
  
  <p><code>{ FACEBOOK_NON_JSON_RESULT: '����\u0000\u0010JFIF\u0000\u0..}</code></p>
  
  <p>Using <a href="https://developers.facebook.com/tools/explorer/?method=GET&amp;path=me%2Fpicture%3Ffields%3Dredirect%2Curl&amp;version=v2.8" rel="nofollow noreferrer">Graph API Explorer</a> returns correct results (JSON with picture url).</p>
  
  <p>Authentication is done correctly and all other calls return expected data.</p>
  
  <p>Here is my code: </p>
  
  <pre><code>const request = new GraphRequest(
    '/me/picture',
    {
      accessToken: 'MY_ACCESS_TOKEN_HERE',
      parameters: {
        fields: {
          string: 'redirect,url'
        }
      }
    },
    (error, result) =&gt; {
      console.log(result);
    });
  
  new GraphRequestManager().addRequest(request).start();
  </code></pre>
  
  <p>Any ideas what i can be doing wrong? 
  Thanks.</p>
