请求人体检测问题[关闭]

我正在编写自己的消息传递应用程序，结果发现消息奇迹般地没有到达服务器。

在应用程序控制台中，我看到我想要发送的内容：

        {"DataTime": "17:06:08",
         "JwtToken":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6IjY2YzllMzM5NzcwNWU1MjA5ZGUxNzZlNyIsIm5hbWUiOiIxMjMiLCJpYXQiOjE3MjY4NTE1OTl9.mmMZmKBlJRUfgjpGzMr9_YFz9qTGE1iGIuOKBWy6fRo",
         "recipient": "admin ", 
         "sender": "66c9e3397705e5209de176e7", 
         "text": "123", 
         "type": "NewMessage"}

发送到 WebSoket（处理传输到特定链接的请求）后，服务器发出请求，我收到的数据与从应用程序收到的数据相同，但是当此数据传输到服务器时，各处的所有数据都会丢失，并且服务器崩溃。这是服务器请求代码（nodejs）：

app.post('/api/SentMessage', async (res, req) => {
    console.log("Sending message");
    console.log(req.body)
    const {DataTime, JwtToken, recipient, sender, text} = req.body;

    try {
        const user = await User.findOne({ Jwt: JwtToken }).lean();
        if (!user) {
            console.log("Не найден пользователь или неправильный токен");
            return res.status(403).json({ success: false, message: 'Ошибка в токене' });
        }
        try {
            const SentMess = await SendingMess(text, sender, recipient, DataTime);
            console.log("Новое сообщение:", SentMess);
            res.status(200);
        } catch (error) {
            console.error("Ошибка сохранения сообщений:", error);
            res.status(405).json({ success: false, message: "Что-то пошло не так при поиске сообщений" });
        }
        
    } catch (error) {
        console.log(error);
        res.status(500).json({success:false, message:"При отправке сообщения произошла ошибка"})
    }

});

并且在收到处理请求后，会产生以下错误：

Sending message

    const {DataTime, JwtToken, recipient, sender, text} = req.body;
           ^

我以为问题出在WebSockete上，但是通过postman发送请求导致服务器崩溃
