use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;

final class SetonoSyliusReserveStockExtension extends Extension

    public function load(array $config, ContainerBuilder $container): void
    {
        $config = $this->processConfiguration($this->getConfiguration([], $container), $config);

It seems like $this->getConfiguration(array(), $container) can also be of type null; however, parameter $configuration of Symfony\Component\DependencyInjection\Extension\Extension::processConfiguration() does only seem to accept Symfony\Component\Config\Definition\ConfigurationInterface, maybe add an additional type check?

        $container->setParameter('setono_sylius_reserve_stock.ttl', $config['ttl']);

        $loader = new XmlFileLoader($container, new FileLocator(__DIR__ . '/../Resources/config'));
        $loader->load('services.xml');
    }
