erlang2facebook friends_get does not work

[Salonee Sinha Roy]

I have the following piece of code , where I attempt to pull the users list
of friends from facebook

{ok,{friends_get_response,Attrs,FriendIds}} =
facebook:friends_get(Session),
This code appears to fail continously for no apparent reason. The errror
message is . Any help would be greatly appreciated.
