ReferenceError：未定义章节

Question

一旦在我的收藏“我的英雄学院”中创建了一个文档，我就会尝试向特定设备发送通知。当我尝试部署该功能时，我收到以下错误 -

Error: Error occurred while parsing your function triggers.

ReferenceError: chapter is not defined

代码：

const functions = require('firebase-functions');
const admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);

var msgData;
var token = "####";

exports.offerTrigger = functions.firestore.document(
    'My Hero Academia'/{chapter}
    ).onCreate((snapshot,context) => {
        msgData = snapshot.data();
        var payload = {
            "notifications": {
                "title": "A new chapter has been released",
                "body": "Read chapter " + msgData.number + " now!",
                "sound": "default"
            }
        }

        return admin.messaging().sendToDevice(token,payload).then((response) => {
            console.log('Pushed notification');
        }).catch((error) => {
            console.log(error);
        })
    })

显然，我已经隐藏了我的令牌。正如错误所说，没有定义章节。但是 {chapter} 不是用来指代将要创建的新文档吗？

编辑：

改变这个：

functions.firestore.document(
    'My Hero Academia'/{chapter}
    ).onCreate((snapshot,context) => {

进入这个：

functions.firestore.document('My Hero Academia/{chapter}')
.onCreate((snapshot,context) => {

你应该有' 也超过{chapter}：
