Override Router

Hi folks!

I'm trying to override the router.

From what I can make out, the best way to do this is to edit the service first.

So, in my app/Services.php, I have the following:-

PHP Code:

<?php

namespace Config;

use CodeIgniter\Config\BaseService;

class Services extends BaseService
{
 
    public static function router(RouteCollectionInterface $routes = null, Request $request = null, bool $getShared = true)
    {
        if ($getShared) {
            return static::getSharedInstance('router', $routes, $request);
        }

        $routes = $routes ?? static::routes();
        $request = $request ?? static::request();

        return new Router($routes, $request);
    }
} 


The function is copied directly from the system services file. So, in theory, as it's unchanged, it should work as usual?

However, I now get the following error:- 

Argument 1 passed to Config\Services::router() must be an instance of Config\RouteCollectionInterface or null, instance of CodeIgniter\Router\RouteCollection given, called in /var/www/vhosts/creative-spectrum.co.uk/public_html/micronet/system/CodeIgniter.php on line 807
