Nonce is always empty when using spatie/laravel-csp with Laravel and vite.js – PHP

I’m facing an issue that the "nonce" value is always empty when using spatie/laravel-csp (v2.8.2) with vite and laravel framework (9.44). I followed the instructions on github page. Here is my configuration:

app/http/Kernel.php

protected $middlewareGroups = [
        'web' => [
            ...
            SpatieCspAddCspHeaders::class
        ],

config/csp.php

'nonce_generator' => AppSupportLaravelViteNonceGenerator::class,

The used policy uses the nonce directive from basic policy by spatie.

LaravelViteNonceGenerator.php

namespace AppSupport;

use IlluminateSupportStr;
use IlluminateSupportFacadesVite;
use SpatieCspNonceNonceGenerator;

class LaravelViteNonceGenerator implements NonceGenerator
{
    public function generate(): string
    {
        return Vite::useCspNonce();
    }
}

app.blade.php in my head

    @viteReactRefresh
    @vite('resources/js/app.jsx')

When I use @nonce directive, the nonce has the same random string value like shown in Content-Security-Policy header on my page but the script tag does not get it as attribute.

Some further information:
vite: 3.2.4
@vitejs/plugin-react: 2.2.0
laravel-vite-plugin: 0.6.1

What am i doing wrong?
