Laravel 5.3 : pagination orm left join query results gives empty

I am trying to paginate a left join query result

here is my code

$result = Art::leftJoin('cushbu_users',function ($join){
                $join->on('cushbu_arts.artist_id', '=', 'cushbu_users.id');
               })
                ->where('category',$category)
                ->where('status',1)
                ->paginate(1,[
                    'cushbu_users.name as artistName',
                    'cushbu_arts.id',
                    'cushbu_arts.title',
                    'cushbu_arts.slug',
                    'cushbu_arts.width',
                    'cushbu_arts.height',
                    'cushbu_arts.depth',
                    'cushbu_arts.base_price',
                    'cushbu_arts.cropped_image',
                    'cushbu_arts.category'
                ]);
     dd($result);

But the collections give empty result

LengthAwarePaginator {#221 ▼ #total: 3 #lastPage: 3 #items: Collection {#204 ▼ #items: [] } #perPage: 1 #currentPage: 5 #path: "http://localhost/cushbu/public/category/Painting" #query: [] #fragment: null #pageName: "page"
