无法部署云功能

Question

当我部署函数时，出现错误，我尝试了所有方法，但无法解决问题我正在写推送通知的功能我认为我写的代码是正确的，但我不确定它是否正确

这是我在CMD 上收到的错误

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! functions@ lint: `eslint .`
npm ERR! Exit status 1

这是我在index.js 中看到的代码

'use strict'
const functions = require('firebase-functions');
const admin = require ('firebase-admin');
admin.initializApp(functions.config().firebase);


exports.sendNotification=
functions.database.ref('/Notifications/${receiver_id}/{notification_id}')
.onWrite(event =>{
const receiver_id = event.params.receiver_id;
const notification_id = event.params.notification_id;
console.log('We have a Notifications to send to :', 
receiver_id);
if (!event.data.val())
{
return console.log('A Notifications has been deleted from 
the database', notification_id);
}
const deviceToken = 
admin.database().ref(`/Users/${receiver_id}/device_token`)
.once('value');
return deviceToken.then(response =>
{
const token_id = result.val();
const payload =
{
notifications;
title: "Friend Request",
body: "You have a New Friend",
icon: "default"
return admin.messaging().sendToDevice(token_id, payload)
.then(response =>{
console.log('This was the notification feature.');
});
};
});
});

您使用的是什么版本的云函数？如果您使用的是1.0或更高版本，那么代码中有几件事需要解决。首先，指南指出实时数据库.onWrite触发器传递两个参数：更改和上下文。此外，路径中不应该有"$"。此外，parameters对象似乎包含了所有代码的后半部分。在有效载荷中，它写着"notifications；"，但我不确定应该是什么。看起来它应该与指南中显示的有效载荷相匹配。可能还有其他错误我没有发现。如果是我，我可能会尝试获得一个更简单的函数来成功部署，然后一块一块地添加到它中。

exports.sendNotification = functions.database.ref('/Notifications/{receiver_id}/{notification_id}')
.onWrite((change, context) => {
const receiver_id = context.params.receiver_id;
const notification_id = context.params.notification_id;
console.log('We have a Notifications to send to :', receiver_id);
if (!change.after.val()) {
return console.log('A Notifications has been deleted from the database', notification_id);
}
const deviceToken = admin.database().ref(`/Users/${receiver_id}/device_token`)
.once('value');
return deviceToken.then(response => {
const token_id = result.val();
const payload = {
notification: {
title: 'Friend Request',
body: 'You have a New Friend',
icon: 'default'
}
};
return admin.messaging().sendToDevice(token_id, payload)
.then(response => {
console.log('This was the notification feature.');
});
});
});
