Cannot access id on Eloquent model

Question

I have an api endpoint that gives a web chat on my front end a list of online friends, however the user id is not included in my json, I would like to include the user_id in my json, but on my controller when I add the print_r like so...

public function index()
{
    $users = $this->friendService->getFriendsList();
    print_r($users);die();
    $json = Fractal::create()
        ->collection($users)
        ->transformWith(new FriendTransformer())
        ->toJson();

    return $json;
}

This the print_r output, how can I make the id accessible to my transformer?
