koala - how to get users facebook friends

hi, im using the koala gem, and i woudl like to display a list of friends, meaning the friend of the user being displayed.
->> /user/:id/friends

this give me only an empty array

friends = @graph.get_connections(“me”, “friends”, api_version: ‘v2.0’)

not sure…pls help


Where in the call is the current user referenced?


that’s what I’m not clear about. what reference do I have to pass instead of ‘me’?
I got the oath working and users can login via fb, but not sure what to pass here…what am I missing?
