Hi, I received this error:

The version of PHP and OS is: PHP 7.4.33 and Windows 10

Can someone help me?

This is my SalesByCustomer.php file: <?php

require_once "../koolreport/core/autoload.php"; require_once "../configBancoDados/config_db.php";

class SalesByCustomer extends \koolreport\KoolReport {

protected function settings()
{
    global $host_bd, $nome_bd, $usuario_bd, $senha_bd;
    return array(
        "dataSources"=>array(
            "mysql_datasource"=>array(
                "connectionString"=>"mysql:host=$host_bd;dbname=$nome_bd",
                "username"=>"$usuario_bd",
                "password"=>"$senha_bd",
                "charset"=>"utf8",
            ),
            "sales"=>array(
                "class"=>'\koolreport\datasources\CSVDataSource',
                "filePath"=>"orders.csv",
            ),
        )
    );
}

protected function setup()
{
    global $nome_bd;
    $this->src('mysql_datasource')
        ->query("SELECT customerName, dollarSales FROM $nome_bd.orders")
        ->params(array(":status"=>"completed"))
        ->pipe($this->dataStore('salesByCustomer'));
}

}

And here is my SalesByCustomer.view.php file:

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