Php 有没有办法让 Symfony 控制器什么也不返回

我使用symfony 6.1和PHP8.1.我想知道是否有一种方法可以让symfony控制器不返回任何内容.原因是我用的是Botman，不幸的是它自己给客户发了一个回复...因此，我需要让我的控制器不返回任何内容.

/**
 * @param Request $request
 *
 * @return Response
 */
#[Route('/botman', methods: 'POST')]
public function test(Request $request): Response
{
    DriverManager::loadDriver(WebDriver::class);
    $adapter = new FilesystemAdapter();

    $botman = BotManFactory::create([], new SymfonyCache($adapter), $request);

    $botman->hears('hello', static function (BotMan $bot) {
        $bot->reply('Yoooooo'); //<- Send a response to the client
    });

    $botman->fallback(static function (BotMan $bot) {
        $bot->reply('try again'); //<- Send a response to the client
    });

    $botman->listen(); // Launch the maching callback

    return new Response(); //Crash because a response have already been sent
}

这就是我在浏览器判断器上得到的信息.

{
    "status": 200,
    "messages": [
        {
            "type": "text",
            "text": "try again",
            "attachment": null,
            "additionalParameters": []
        }
    ]
}{
    "type": "https:\/\/tools.ietf.org\/html\/rfc2616#section-10",
    "title": "An error occurred",
    "status": 500,
    "detail": "Warning: Cannot modify header information - headers already sent by (output started at C:\\Users\\cimba\\Documents\\botman\\vendor\\symfony\\http-foundation\\Response.php:1265)",
    "class": "ErrorException",
    "trace": [...]
}

我唯一的解决方案是exit();或die();，而不是return，但我认为它不适合生产…也许有一种方法可以避免Botman发送它的响应，或者告诉symfony我希望我的控制器不返回任何东西(因为Botman没有symfony).
