я хочу отправить приветственное уведомление, когда пользователь входит в систему с помощью Cloud-Function с аутентификацией firebase, поэтому я использую nodejs CLI и запускаю код
мой индекс. js файл 'use strict';
const functions = require('firebase-functions');
const nodemailer = require('nodemailer');
// Configure the email transport using the default SMTP transport and a GMail account.
// For Gmail, enable these:
// 1. https://www.google.com/settings/security/lesssecureapps
// 2. https://accounts.google.com/DisplayUnlockCaptcha
// For other types of transports such as Sendgrid see https://nodemailer.com/transports/
// TODO: Configure the `gmail.email` and `gmail.password` Google Cloud environment variables.
const gmailEmail = functions.config().gmail.email;
const gmailPassword = functions.config().gmail.password;
const mailTransport = nodemailer.createTransport({
service: 'gmail',
auth: {
user: gmailEmail,
pass: gmailPassword,
},
});
// Your company name to include in the emails
// TODO: Change this to your app or company name to customize the email sent.
const APP_NAME = 'Cloud Storage for Firebase quickstart';
// [START sendWelcomeEmail]
/**
* Sends a welcome email to new user.
*/
// [START onCreateTrigger]
exports.sendWelcomeEmail = functions.auth.user().onCreate((user) => {
// [END onCreateTrigger]
// [START eventAttributes]
const email = user.email; // The email of the user.
const displayName = user.displayName; // The display name of the user.
// [END eventAttributes]
return sendWelcomeEmail(email, displayName);
});
// [END sendWelcomeEmail]
// [START sendByeEmail]
/**
* Send an account deleted email confirmation to users who delete their accounts.
*/
// [START onDeleteTrigger]
exports.sendByeEmail = functions.auth.user().onDelete((user) => {
// [END onDeleteTrigger]
const email = user.email;
const displayName = user.displayName;
return sendGoodbyeEmail(email, displayName);
});
// [END sendByeEmail]
// Sends a welcome email to the given user.
async function sendWelcomeEmail(email, displayName) {
const mailOptions = {
from: `${APP_NAME} <noreply@firebase.com>`,
to: email,
};
// The user subscribed to the newsletter.
mailOptions.subject = `Welcome to ${APP_NAME}!`;
mailOptions.text = `Hey ${displayName || ''}! Welcome to ${APP_NAME}. I hope you will enjoy our service.`;
await mailTransport.sendMail(mailOptions);
console.log('New welcome email sent to:', email);
return null;
}
// Sends a goodbye email to the given user.
async function sendGoodbyeEmail(email, displayName) {
const mailOptions = {
from: `${APP_NAME} <noreply@firebase.com>`,
to: email,
};
// The user unsubscribed to the newsletter.
mailOptions.subject = `Bye!`;
mailOptions.text = `Hey ${displayName || ''}!, We confirm that we have deleted your ${APP_NAME} account.`;
await mailTransport.sendMail(mailOptions);
console.log('Account deletion confirmation email sent to:', email);
return null;
}
я передаю этот код https://github.com/firebase/functions-samples/blob/master/quickstarts/email-users/functions/index.js
, но после запуска кода я получаю сообщение об ошибке

Я также разрешаю менее безопасные приложения Из вашей учетной записи Google, а также сделал 2 пошаговой проверки 
, но все равно получил ошибку
Я прочитал все «Подобные вопросы» здесь в stackoverflow и не знаю, нужно ли мне что-нибудь еще или если я делаю что-то плохое
