Laravel Mongodb Error

I just started converting mysql to nosql (Mongodb) and after convertion it's showing some error like this:

Trying to get property 'size' of non-object 

This is the code below i used

class PanelController extends Controller
{

    public function index()
    {
       $userid = Auth::user()->id;
       $users = DB::collection('Booking')->where('Uid', '>=', $userid)->get();
      return view('panel.main')->with('records',$users);
    }
}

In the view i'm using like this,

@foreach ($records as $rec)

@endforeach

So please someone can help me with this would be much appreciated.
