Dashboard Application ErrorException: Undefined index getKDR() returns null #3208

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


use \koolreport\dashboard\Application;

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

Below is my code for the view file.

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


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!

Let not using the view file to host the dashboard app, let put it directly inside your action like this:

    require_once __DIR__ . "/../../models/dashboards/CoriApp.php"; //Put on top of your controller class
    public function actionCoriDashboard(){

Let me know if there is any difference.

Is there not instructions for setting this up in Yii2?

If you intend to use KoolReport Dashboard in Yii2, pls config your App class with Yii2 trait like in the following docs:


If there's any issue pls let us know. Tks,

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

This original error is solved by changing all the "CoriApp" name to "App" only.
