method injection throws League\Container\Exception\NotFoundException

[nixoncode]

Am having an issue with making the App run with method Injection 💉 enabled.

This is the only code I have on index.php file

use Jenssegers\Lean\App;
use Slim\Http\Request;
use Slim\Http\Response;
use Slim\Settings;

require __DIR__ . '/../vendor/autoload.php';

$app = new App();

$container = $app->getContainer();

$container->get(Settings::class)->replace([
    'displayErrorDetails' => true,
]);

// when this is commented, It doesn't work, at all
$app->getContainer()->get(Settings::class)->set('methodInjection', false);

$app->get('/hello/{name}', function (Request $request, Response $response) {
    $name = $request->getAttribute('name');
    return $response->write('Hello, ' . $name);
});

$app->run();

Here is the Error

Slim Application Error
The application could not run because of the following error:

Any Ideas on what I might be doing wrong?
