Module not registered in the application container.

[redeemerr]

Hi,
I am trying to use the Module in a new phalcon app but getting this error don't understand why :(

Module 'Frontend' isn't registered in the application container

#0 [internal function]: Phalcon\Application\AbstractApplication->getModule()
#1 /home/umair/PhpstormProjects/new/src/Bootstrap.php(128): Phalcon\Mvc\Application->handle()
#2 /home/umair/PhpstormProjects/new/src/Bootstrap.php(117): App\Bootstrap->getOutput()
#3 /home/umair/PhpstormProjects/new/public/index.php(21): App\Bootstrap->run()
#4 {main}

here is the code :

// Bootstrap.php
        $this->app = new Application;
        $this->app->setEventsManager($this->di->getShared('eventsManager'));
        $this->app->registerModules([
            [
                'className' => 'App\Domain\Frontend',
                'path' => dirname(__DIR__) . '/src/Domain/Frontend/Module.php',
            ],
            [
                'className' => 'App\Domain\Api',
                'path' => dirname(__DIR__) . '/src/Domain/Api/Module.php',
            ],
        ]);
        $this->app->setDefaultModule('Frontend');
        die(var_dump($this->app->getDefaultModule())); // string(8) "Frontend" 
        $this->app->setDI($this->di);
        $this->setupEnv();

<?php
// Index.php
declare(strict_types=1);

defined('BASE_PATH') || define('BASE_PATH', dirname(__FILE__, 2) . '/');
defined('APP_PATH') || define('APP_PATH', BASE_PATH . '../src');

$autoload = dirname(__DIR__) . '/src/library/vendor/autoload.php';
if (!is_file($autoload)) {
    die('run composer install.');
}

require_once $autoload;


(new \Phalcon\Loader())->registerDirs([__DIR__ . '../src'])
    ->registerNamespaces(['App' => __DIR__ . '../src'])
    ->register();


try {
    (new App\Bootstrap(dirname(__FILE__, 2)))->run();
} catch ( \Exception $Exception) {
    die($Exception->getMessage() . "\n" . $Exception->getTraceAsString());
}

Please try registering the modules using an associative array like the example in the docs:

// Register the installed modules
$application->registerModules(
    [
        'frontend' => [
            'className' => 'Multiple\Frontend\Module',
            'path'      => '../apps/frontend/Module.php',
        ],
        'backend'  => [
            'className' => 'Multiple\Backend\Module',
            'path'      => '../apps/backend/Module.php',
        ]
    ]
);
