It seems like $this->getParsedBody() ?? array() can also be of type Koded\Http\Interfaces\Response; however, parameter $values of Koded\Stdlib\Immutable::__construct() does only seem to accept array, maybe add an additional type check?

        if (0 === $body->count()) {
            return null;
        }

        if (empty($errors = $validator->validate($body))) {
            return null;
        }

        $errors['code'] = (int)($errors['code'] ?? StatusCode::BAD_REQUEST);
        return new ServerResponse(json_serialize($errors), $errors['code']);
    }
