Graph API - /apprequests seems to return an empty JSON array every time

When I use

https://graph.facebook.com/(userid goes here)/apprequests?access_token=(user access_token goes here)

it returns an empty JSON array like so:

{
   "data": [

   ]
}

Even though there ARE app requests.

These people were having the same problem, but didn't get their question answered either:

What am I doing wrong?

I开发者_StackOverflow tried POSTing and GETing requests with the Graph API Explorer, and THEY don't return an empty JSON array (however they only return the app requests POSTed by Graph API Explorer, not the requests for my app....I imagine this is to be expected however). Could this have something to do with my app being in sandbox mode? Does /apprequests work for anyone else's sandboxed app?

A few weeks back (around mid-september 2011), it was possible to get the requests with https://graph.facebook.com/me/apprequests?access_token={user_access_token}.

It does not seem possible today anymore. This call returns an empty data structure now.

Instead, calling https://graph.facebook.com/{user_id}/apprequests?access_token={app_access_token} does seem to work.

apprequests connection expect an app access token.
