Unable to get FB Pages with valid access token

[junaidatique]

I am using graph api v2.12. I am trying to get user pages for my app, when user allow all the permissions. App works fine for the auth part and user do allow all the permissions. The app get valid access token but when I make api call to get the pages I get this unexpected error.

// using facebook php sdk

 $response = $fb->get('/me?fields=accounts', $access_token);

// for my own account I always get status code 500
// response
[httpStatusCode:protected] => 500

Happens to me as well, but only the first request returns error. Could you provide a link to the bug you opened on FB please?
