Undefined offset: 0: Laravel Error on LIVE Server

In my Laravel Controller, I'm importing csv to my db, I query SQL get products_name and then insert product_name to my order table. The CODE work Perfect on my xampp server, it was when I deploy to live server (Cpanel) that I gives Error.

$products_name = DB::table('products_description')
->where('products_id','=', $importData[0])->pluck('products_name');


OrdersProduct::create(
                       array
                        (
                            "products_id"=>$importData[0],
                            "products_name"=>$products_name[0],
                            "products_quantity"=>$importData[1],
                        )
                    );

My Larevel Log is showing Error Msg: production.ERROR: Undefined offset: 0

When I used return $products_name[0], It displays the Product Name... but when I tried to Create OrderProducts, it generates error. Note there is content is the products_name and it works fine on my localhost, only when I deployed to server I get error.
