Routing to a module adds App\Controllers to the route

I need a little help to get a module to load correctly.

My problem is that the handler generated for my defined route seems to prefix App\Controllers to the route in the module folder

My Directory Structure is as follows:

Code:

├── app
│  ├── Config
│  ├── Controllers
│  ├── ...All the other CI4 folders
├── modules
│  ├── admin
│  │  ├── Config
│  │  ├── Controllers
│  │  ├── Models
│  │  ├── Views

\app\Config\Autoload.php

PHP Code:

<?php

namespace Config;

use CodeIgniter\Config\AutoloadConfig;

class Autoload extends AutoloadConfig
{
    public $psr4 = [
        APP_NAMESPACE => APPPATH, // For custom app namespace
        'Config'      => APPPATH . 'Config',
        'Modules'    => ROOTPATH . 'modules',
        'Modules\admin'    => ROOTPATH . 'modules\admin',
    ];

    public $classmap = [];

    public $files = [];

    public $helpers = [];
} 


\app\Config\Routes.php

PHP Code:

<?php

namespace Config;

$routes = Services::routes();

$routes->setDefaultNamespace('App\Controllers');
$routes->setDefaultController('Home');
$routes->setDefaultMethod('index');
$routes->setTranslateURIDashes(false);
$routes->set404Override();

$routes->get('/', 'Home::index');
$routes->get('/reachability', 'Reachability::index');

if (is_file(APPPATH . 'Config/' . ENVIRONMENT . '/Routes.php')) {
    require APPPATH . 'Config/' . ENVIRONMENT . '/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');
  }
} 


\modules\admin\Config\Routes.php

PHP Code:

<?php

$routes->get('/admin', 'Modules\admin\Controllers\User::validate'); 


\modules\admin\Controllers\User.php

PHP Code:

<?php

namespace Modules\admin\Controllers

class User extends \CodeIgniter\Controller {

    public function validate() {
        echo "The validate admin user page";
    }
} 


In the CI4 debug toolbar from http://localhost:8080/ (and http://localhost:8080/reachability):

Code:

MATCHED ROUTE
Directory:
Controller: \App\Controllers\Home
Method: index
Params: 0 / 0

DEFINED ROUTES
Method Route Handler
GET / \App\Controllers\Home::index
GET reachability \App\Controllers\Reachability::index
GET admin \App\Controllers\Modules\admin\Controllers\User::validate

From http://localhost:8080/admin I only get a 404 error:

Controller or its method is not found: \App\Controllers\Modules\admin\Controllers\User::validate

I do not get a CI4 debug toolbar icon on this url.

I suspect it is something I don't understand about namespaces. I am new to CI.

Thank you for any assistance

PHP Code:

'Modules\admin'    => ROOTPATH . 'modules\admin',

// should be
'Modules\admin'    => ROOTPATH . 'modules/admin', 


What did you Try? What did you Get? What did you Expect?
