当我尝试在Firebase中部署此错误时，错误不断：“命令以非零退出代码1终止”。请帮助我解决这个问题。我将非常感谢您。我想制作一个用户可以在其中收到通知的应用程序，当他单击通知时，它应该打开一个新活动。
'use strict'
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
exports.sendNotification =
functions.database.ref('/notifications/{user_id}/{notification_id}').onWrite(event => {
const user_id = event.params.user_id;
const notification_id = event.params.notification_id;
console.log('We have a notification from : ', user_id);
if(!event.data.val()){
return console.log('A Notification has been deleted from the database : ', notification_id);
}
const fromUser = admin.database().ref(`/notifications/${user_id}/${notification_id}`).once('value');
return fromUser.then(fromUserResult => {
const from_user_id = fromUserResult.val().from;
console.log('You have new notification from : ', from_user_id);
const userQuery = admin.database().ref(`Users/${from_user_id}/name`).once('value');
const deviceToken = admin.database().ref(`/Users/${user_id}/device_token`).once('value');
return Promise.all([userQuery, deviceToken]).then(result => {
const userName = result[0].val();
const token_id = result[1].val();
const payload = {
notification: {
title : "New Friend Request",
body: `${userName} has sent you request`,
icon: "default",
click_action : "in.tvac.akshaye.lapitchat_TARGET_NOTIFICATION"
},
data : {
from_user_id : from_user_id
}
};
admin.messaging().sendToDevice(token_id, payload).then(response => {
console.log('This was the notification Feature');
});
});
});
});
