Facebook Graph API - Get Photos - Unsupported Get Request

I am testing the Facebook API through their explorer. I managed to get my channel using me / home. However, I want to get some data from the uploaded photos. When I read other posts, I need to rerun the request using the object_id in the POST object.

This only works for publicly available images. Whenever I try to do this on a friend's photo, I get:

{
  "error": {
    "message": "Unsupported get request. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api", 
    "type": "GraphMethodException", 
    "code": 100
  }
}

      

        
        
        
      

    

One of them was a photograph of my wife. I checked her privacy setting, as far as I can see, it does not block third party APIs. How can I get information about the details of the messages returned by the API in me / home?

I know it doesn't work for photos with unique resolutions (like tags in them), but I've only tested it with photos that were only available to those friends. Tested about 10, none of them work. How is this possible?
