Como enviar e-mail usando Cloud Functions do Firebase com um projeto Ionic 3+ e Nodemailer

index.js

'use strict';
const functions  = require('firebase-functions');
const nodemailer = require('nodemailer');
const cors = require('cors')({origin: true});

let url = "smtps://<SEU-EMAIL>%40gmail.com:"+encodeURIComponent('<SUA-SENHA>') + "@smtp.gmail.com:465";
let transporter = nodemailer.createTransport(url);

exports.enviarEmail = functions.https.onRequest((req, res) => {
  cors(req, res, () => {
    let remetente = '"Adson Rocha" <email@gmail.com>';

    let assunto = req.body['assunto'];
    let destinatarios = req.body['destinatarios']; // lista de e-mails destinatarios separados por ,
    let corpo = req.body['corpo'];
    let corpoHtml = req.body['corpoHtml'];

    let email = {
        from: remetente,
        to: destinatarios,
        subject: assunto,
        text: corpo,
        html: corpoHtml
    };

    transporter.sendMail(email, (error, info) => {
        if (error) {
          return console.log(error);
        }
        console.log('Mensagem %s enviada: %s', info.messageId, info.response);
    });
  });
});

Olá tudo bem?

Estou enfrentando este problema ao fazer o deploy da função:

Deployment error.
Failed to initialize region (action ID: 2effcce4c12aa6d3): Function deployment failed because the billing account is not available.


Functions deploy had errors with the following functions:
        enviarEmail


To try redeploying those functions, run:
    firebase deploy --only "functions:enviarEmail"


To continue deploying other features (such as database), run:
    firebase deploy --except functions

Error: Functions did not deploy properly.

Olá, Você precisa habilitar as cobranças na sua conta firebase. Em ter., 12 de jan. de 2021 às 21:26, Alberto Vieira de Lima < notifications@github.com> escreveu:
