title: Koala::Facebook::ClientError Exception: type: GraphMethodException, code: 100, message: Unsupported get request
body: <p>I did research on this issue, however, nothing worked for me.</p>
  
  <p>I am using Facebook Realtime subscription and graph API to track my facebook page (using page token).</p>
  
  <p>When a user posts a photo/video I am getting following data pushed by fb to my server:</p>
  
  <pre><code>{"field"=&gt;"feed",
   "value"=&gt;
    {"item"=&gt;"photo",
     "verb"=&gt;"add",
     "photo_id"=&gt;302522856593533,
     "post_id"=&gt;"824413870916335_302522856593533",
     "sender_id"=&gt;100005074631221}}
  </code></pre>
  
  <p>When I use <code>post_id (824413870916335_302522856593533)</code> to make call to graph API for fetching details of the post, I am encountering following error:</p>
  
  <blockquote>
    <p>*** Koala::Facebook::ClientError Exception: type: GraphMethodException, code: 100, message: Unsupported get request.
    Please read the Graph API documentation at
    <a href="https://developers.facebook.com/docs/graph-api" rel="nofollow noreferrer">https://developers.facebook.com/docs/graph-api</a> [HTTP 400]</p>
  </blockquote>
  
  <p>However, <strong>if user posts without photo/video, I am able to get post details successfully</strong>. In case, admin posts photo/video, I am able to get details of that post too.</p>
  
  <p>I am sure about the correctness of page token and code. I think, there must be something related to settings.</p>
