ReferenceError:未定义章节

Question

一旦在我的收藏集"我的英雄学院"中创建了文档，我将尝试向特定设备发送通知。当我尝试部署该功能时，我会得到以下错误-

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);
})
})

很明显，我把我的代币藏起来了。正如错误所说，章节没有定义。但是，{章}不是用来指代将要创建的新文档吗？

编辑：

Answer 1

更改此项：

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}:
