Laravel Spark - missing PHP file PreventRequestsDuringMaintenance - laravel

Question

I have an old version of Spark running so decided to upgrade my license and start testing a new installation. First, I installed a vanilla Laravel, that worked.
Next, I followed the documentation from https://spark.laravel.com/docs/11.0/installation and I am on Ubuntu 18.04. There were some issues with an older version of node and npm but I finally have them figured out. All commands are successfully, so after doing PHP artisan migrate I checked the website but I am seeing:
Target class [App\Http\Middleware\PreventRequestsDuringMaintenance] does not exist.
Illuminate\Container\Container::build
vendor/laravel/framework/src/Illuminate/Container/Container.php
And indeed, when I checked the folder:
root#spark10:/var/www/html/spark/app/Http/Middleware# ls -al
total 44

Interestingly, when I examine the PreventRequestsDuringMaintenance.php online, I see:
https://github.com/laravel/laravel/commit/e471dd1cf09907b2d325f5ef4a9aefc4b1f2e5c5#diff-f98b07c0f713c816a5c288db58fcd03aab070df160a3bf47b6feb035d3f8ca2c
that it is renamed from CheckForMaintenanceMode to PreventRequestsDuringMaintenance
I created a new file PreventRequestsDuringMaintenance.php
namespace App\Http\Middleware;
use Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode as Middleware;
class PreventRequestsDuringMaintenance extends Middleware
{
/**
* The URIs that should be reachable while maintenance mode is enabled.
*
* #var array
*/
protected $except = [
//
];
}
And while I am writing this question, I see I messed up some names and after fixing that I see the Spark login. So I fixed it already, still posting this question because it might help some other poor chap.
