Laravel 12 require additional route files

In Laravel 8 it was possible to include additional route files with the require base_path parameter

//routes/web.php

Route::middleware(['web'])->group(function () { require base_path('routes/link/webhook.php'); });

php artisan route:cache responds that

Error: require(webhook): Failed to open stream: No such file or directory

This fails to work with require . DIR . '/link/webhook.php'; as well

Error: require(webhook): Failed to open stream: No such file or directory

The documentation recommends using the app.php function

// laravel.com/docs/12.x/routing - bootstrap/app.php

use Illuminate\Support\Facades\Route;

->withRouting(

web: __DIR__.'/../routes/web.php',
commands: __DIR__.'/../routes/console.php',
health: '/up',
then: function () {
    Route::middleware('web')
        ->group(base_path('routes/link/webhooks.php'));
},

)

php artisan route:cache responds

Error: require(webhook): Failed to open stream: No such file or directory

an ls -s routes/link/webhook.php responds with the filename and I have already tried to chmod -R 777 routes and chown -R user:user routes

When the path is made incorrect it lists the entire incorrect path: require base_path('routeslink/webhook.php');

/var/www/html/laravel-project/routeslink/webhook.php cannot be found but when fixed it returns

Error: require(webhook): Failed to open stream: No such file or directory

I have also tried listing the route in the RouteServiceProvider by the same syntax but it still returns

Error: require(webhook): Failed to open stream: No such file or directory

If i remove all requires and changes to the bootstrap/app.php and RouteServiceProvider.php php artisan route:cache works well.

I have also tried to composer dump-autoload php artisan cache:clear

But the app is still unable to find the existing additional route file How can I fix this error?
