Here is the error displayed -

Warning: array_map(): An error occurred while invoking the map callback in C:\laragon\www\asdasd\vendor\league\container\src\Container.php on line 495

( ! ) Fatal error: Uncaught exception 'RuntimeException' with message 'Cannot resolve argument [request], it should be provided within an array of arguments passed to [League\Container\Container::call], have a default value or be type hinted' in C:\laragon\www\asdasd\vendor\league\container\src\Container.php on line 488

( ! ) RuntimeException: Cannot resolve argument [request], it should be provided within an array of arguments passed to [League\Container\Container::call], have a default value or be type hinted in C:\laragon\www\asdasd\vendor\league\container\src\Container.php on line 488

This happens while the route $router->addRoute('POST', '/admin/deals/create', '\MyApp\Controllers\DealController::createAction');
is executed.

Your custom strategy is using the League\Container\Container::call method which attempts to resolve the arguments of the method it is invoking. The problem here is that your MyApp\Controllers\DealController::createAction just accepts $request and $response. If you were to type hint the request and response objects then this would work.

public function createAction(Request $request, Response $response, array $args = [])
{
    echo '<pre>'; var_dump($request);
    echo '<pre>'; var_dump($response);
    echo '<pre>'; var_dump($args);
    exit;
}

👍 It worked.

I used the RequestResponseStrategy in the CustomStrategy's dispatch method, and it worked as well 👍

Thank you so much!
