The call to the method GuzzleHttp\Psr7\Response::getStatusCode() seems un-needed as the method has no side-effects.

        if (array_key_exists('Content-Type', $headers)) {
            $response->headers->set('Content-Type', $headers['Content-Type']);

        $response->setStatusCode($httpResponse->getStatusCode());

        return $response;
