I am trying to set up the quick start in my existing PHP Yii applicaiton. https://www.koolreport.com/docs/dashboard/quick_start/

I get the following error ErrorException: Undefined index: in /opt/bitnami/apache2/htdocs/protected/extensions/koolreport/dashboard/Application.php:360

Looking at the APplication.php code and where the error occurs, I can see that the error occurs because the following code at line 353 returns null $next = $this->request()->nextHandler($this);

Through further debugging I can see taht the getKDR() function inside the Request class returns null. Why does this occur?

Below is my code for the application

<?php

use \koolreport\dashboard\Application;

class CoriApp extends Application
{
    protected function sidebar()
    {
        return [
            "Nonconformity Board"=>CoriBoard::create()
        ];
    }
}

Below is my code for the view file.

<?php
//require_once  "vendor/autoload.php"; //Load library
require_once __DIR__ . "/../../models/dashboards/CoriApp.php";

CoriApp::create()->run();
?>

The library is loaded in my module file of my MVC structure The view file above is loaded through my controller in the code below

    public function actionCoriDashboard(){
        $this->render('coriDashboard', array());
    }

Any help would be appreciated!

Nothing, I get the same error.

Is there not instructions for setting this up in Yii2?

Yeah I have done that. Still doesn't work. You need more instructions for Yii framework. This is not working at all for dashboard.
