hi sorry, could you do a checking for me? this is my index3.php

<?php
require_once "SalesByProduct.php";

$salesByProduct = new SalesByProduct;
$salesByProduct->run()
->cloudExport("SalesByProduct")
->chromeHeadlessio("my key")
->pdf()
->toBrowser("sales_by_product.pdf");
?>

SalesByProduct.php

<?php
require_once "koolreport/autoload.php";
use \koolreport\processes\Group;
use \koolreport\processes\Sort;
use \koolreport\processes\Limit;
class SalesByProduct extends \koolreport\KoolReport
{
    use \koolreport\cloudexport\Exportable;
    use \koolreport\clients\Bootstrap;

    public function settings()
    {
        return array(
            "dataSources"=>array(
                "sales"=>array(
                    "connectionString"=>"mysql:host=localhost;dbname=finalproject",
                    "username"=>"root",
                    "password"=>"",
                    "charset"=>"utf8"
                )
            )
        );
    }

    public function setup()
    {
        $this->src('sales')
        ->query("SELECT product_name,total_sales FROM dbproduct")
        ->pipe(new Group(array(
            "by"=>"product_name",
            "sum"=>"total_sales"
        )))
        ->pipe(new Sort(array(
            "total_sales"=>"desc"
        )))
        ->pipe(new Limit(array(10)))
        ->pipe($this->dataStore('Top_Selling_Product'));
    }
}

this is SalesByProduct.view.php

<?php 
    use \koolreport\widgets\koolphp\Table;
    use \koolreport\widgets\google\BarChart;
?>

<div class="text-center">
    <h1>Sales Report</h1>
    <h4>This report shows top 10 sales product</h4>
</div>
<hr/>

<?php
    BarChart::create(array(
        "dataStore"=>$this->dataStore('Top_Selling_Product'),
        "width"=>"100%",
        "height"=>"500px",
        "columns"=>array(
            "product_name"=>array(
                "label"=>"Product Name"
            ),
            "total_sales"=>array(
                "type"=>"number",
                "label"=>"Sales Amount",
                "prefix"=>"$",
            )
        ),
        "options"=>array(
            "title"=>"Top 10 Selling Product"
        )
    ));
?>
<?php
Table::create(array(
    "dataStore"=>$this->dataStore('Top_Selling_Product'),
        "columns"=>array(
            "product_name"=>array(
                "label"=>"Product Name"
            ),
            "total_sales"=>array(
