title: Not able to get photo via API, which returns 404
body: <p>When I tried to retrieve a Photo using <a href="https://developer.microsoft.com/en-us/graph/graph-explorer" rel="nofollow noreferrer">Graph Explorer</a>, it worked well using the sample account. </p>
  
  <p>But when I sign in with my own account, it was broken.</p>
  
  <p>When I request:</p>
  
  <pre><code>https://graph.microsoft.com/v1.0/me/contacts/{Id}/photo/$value
  </code></pre>
  
  <p>It returnes:</p>
  
  <pre><code>{
      "error": {
          "code": "ErrorItemNotFound",
          "message": "The specified object was not found in the store.",
          "innerError": {
              "request-id": "ad665ca9-9585-4f7a-9dd1-803061d8baba",
              "date": "2018-10-09T15:55:54"
          }
      }
  }
  </code></pre>
  
  <p>I don't know the reason, it confused me.</p>
