I have integrated subreport with daterange filter using laravel ajax loading.
After selecting date range and click "filter" button, i got the following error message
Failed to load resource: the server responded with a status of 404 (Could not find [displayreport] sub report)

This is my code
DashboardReport.php
<?php
namespace App\Reports; use \koolreport\querybuilder\DB; use \koolreport\querybuilder\MySQL; use App\Reports\FilterForm; use App\Reports\DisplayCard; use App\Reports\DisplayReport;
class DashboardReport extends \koolreport\KoolReport {
use \koolreport\laravel\Friendship; 
 use \koolreport\clients\jQuery;
 use \koolreport\core\SubReport;
// By adding above statement, you have claim the friendship between two frameworks
// As a result, this report will be able to accessed all databases of Laravel
// There are no need to define the settings() function anymore
// while you can do so if you have other datasources rather than those
// defined in Laravel.
function settings()
{
    return array(
        "subReports"=>array(
            "displaycard"=>DisplayCard::class,
            "filterform"=>FilterForm::class,
            "displayreport"=>DisplayReport::class,
        )
    );
}
}
?>

    console.log("kames"+$('#dateRange_start').val());
    
    subReport.update("displayreport",{
