我使用Pusher在Nodejs中启动实时。但是我在编码时遇到了一个问题。这是我的问题。

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^

Node.js v18.6.0
[nodemon] app crashed - waiting for file changes before starting...

这是我的代码：

const pusher = new Pusher({
  appId: process.env.PUSHER_APPID,
  key: process.env.PUSHER_KEY,
  secret: process.env.PUSHER_SECRET, 
  cluster: process.env.PUSHER_CLUSTER,
  useTLS: true,
});

const db = mongoose.connection;

db.once('open',  () => {
  const msgCollection = db.collection('chats');
  const msgChangeStream = msgCollection.watch();

   msgChangeStream.on('change', (change) => {  
    if (change.operationType === 'insert') {
      const messageDetails = change.fullDocument; 
      pusher.trigger('messages', 'insert', {
        content: messageDetails.content,
        users: messageDetails.users, 
        sender: messageDetails.sender,  
      }); 
    } else {
      console.log('Error Trigger Pusher');
    }
  });
