Description

Config attribute throws a Illuminate\Contracts\Container\BindingResolutionException if the set value is NULL.

If the value is not NULL, it works as expected.

php artisan app:test-command

   Illuminate\Contracts\Container\BindingResolutionException

Steps To Reproduce

app/Services/TestService.php

namespace App\Services;

use Illuminate\Container\Attributes\Config;

class TestService
{
    public function __construct(
        #[Config('foo.bar')]
        private ?string $bar,
    ) {}

    public function getBar(): ?string
    {
        return $this->bar;
    }
}

app/Console/Commands/TestCommand.php

namespace App\Console\Commands;

use App\Services\TestService;
use Illuminate\Console\Command;

class TestCommand extends Command
{
    protected $signature = 'app:test-command';

    public function handle(TestService $testService)
    {
        $this->info($testService->getBar());
    }
}

config/foo.php

return [
    'bar' => null,
];

so, run php artisan app:test-command.
