Codeigniter 4 - Cannot get my module to work - php

Question

I am trying to get a simple module working. All it does is echo 'test' to a web page but I cannot get it working.
The first thing I did was add the module to app/Config/Autoload.php as follows;
public $psr4 = [
APP_NAMESPACE => APPPATH, // For custom app namespace
'Config' => APPPATH . 'Config',
'Modules\Filemanager' => ROOTPATH . 'modules'
];
Then, I created the following directory structure;
In Modules/Filemanager/Config/Routes.php I have added following route;
<?php
$routes->add('/filemanager/(:any)', 'Modules\Filemanager\Controllers\Filemanager::index');
Lastly, in Modules/Filemanager/Controllers/Filemanager I have the following method:
<?php
namespace Modules\Filemanager\Controllers;
use App\Controllers\BaseController;
class Filemanager extends \App\Controllers\BaseController
{
public function index(){
echo 'test'; die();
}
}
When I go to my browser and enter example.com/filemanager/index I get the following error;
Controller or its method is not found: \App\Controllers\Filemanager::index
Any ideas would be much appreciated.

You've done few things wrong here.
In the App/Config/Autoload.php,
you've written 'Modules\Filemanager' => ROOTPATH . 'modules'
But in your directory structure image, there is no directory with the name 'modules'
Please change the 'Modules' folder name to 'modules'
Change 'Modules\Filemanager' => ROOTPATH . 'modules' to
'Modules' => ROOTPATH . 'modules' in App/Config/Autoload.php
In the Modules/Filemanager/Config/Routes.php
You're using the $routes variable in the below line
$routes->add('/filemanager/(:any)', 'Modules\Filemanager\Controllers\Filemanager::index'); But $routes is not defined anywhere in the file.
Put
if(!isset($routes)) {
$routes = App\Config\Services::routes(true);
}
$routes->get('/filemanager/(:any)', 'Modules\Filemanager\Controllers\Filemanager::index');
It should be $routes->get() instead of $routes->add()
Module level routing will not work until you add these routes in the App\Config\Routes.php file.
To add your modules routes to the app\Config\Routes.php
foreach(glob(ROOTPATH . 'modules/*', GLOB_ONLYDIR) as $item_dir) {
if(file_exists($item_dir . '/Config/Routes.php')) {
require_once($item_dir . '/Config/Routes.php');
}
}
After these changes your code should work.
