trait ConfigResolverAwareTrait
{
    private ?AbstractConfig $config = null;

    public function getConfig(): AbstractConfig
    {
        if ($this->config === null) {
            $this->config = (new ConfigResolver())->resolve($this);
        }

        return $this->config;

The expression return $this->config could return the type null which is incompatible with the type-hinted return Gacela\Framework\AbstractConfig. Consider adding an additional type-check to rule them out.
