        $uri = $this->uri ?? $this->urlGenerator->generate($this->route, $this->parameters);

It seems like $this->route can also be of type null; however, parameter $name of Yiisoft\Router\UrlGeneratorInterface::generate() does only seem to accept string, maybe add an additional type check?

        return $this->responseFactory
            ->createResponse($this->statusCode)
            ->withAddedHeader('Location', $uri);
    }
