Laravel 7.x View-related exception after config:cache

Hi all,

I am a junior php developer and very new to laravel. I have the following problem. I cached my config with php artisan config:cache, the programm broke with error 500 and in the log i saw the exception shown bellow :

local.ERROR: Method Illuminate\View\View::__toString() 
must not throw an exception, caught 
Facade\Ignition\Exceptions\ViewException: Route [homepage.get] not defined.

(View: /var/www/vhosts/sotiris.upgrade/httpdocs/command-center/resources/views/static/includes/header.blade.php) {"exception":"[object] (Symfony\Component\ErrorHandler\Error\FatalError(code: 0): 
Method Illuminate\View\View::__toString() must not throw an exception, caught Facade\Ignition\Exceptions\ViewException: 
Route [homepage.get] not defined.

at /var/www/vhosts/sotiris.upgrade/httpdocs/command-center/vendor/symfony/http-foundation/Response.php:0).

Routes:

/*
|--------------------------------------------------------------------------
| HOME PAGE
|--------------------------------------------------------------------------
*/
Route::get('/',
    [
        'as'            => 'homepage.get',
        'uses'          => 'StaticPagesController@getHomePage'
    ]
);

-bash-4.2$ php artisan route:clear
Route cache cleared!
-bash-4.2$ php artisan config:clear
Configuration cache cleared!
-bash-4.2$

I cleared everything in cache and it worked. Can anyone please help me ? Any steps?? Files to look for ? Anything
