Проблемы с Nodemailer

Я создал аккаунт на etheral email, когда я запускаю этот код

const nodemailer = require('nodemailer')

async function main() {
    let transporter = nodemailer.createTransport({
        host: 'smtp.ethereal.email',
        port: 465,
        secure: true,
        auth: {
            user: '[email protected]',
            pass: 'Tsj3vm3F7KGEaVUuVp'
        },
    });

    await transporter.sendMail({
        from: '"Node js" <[email protected]>',
        to: "<[email protected]>",
        subject: "Hello ✔",
        text: "Hello world?",
        html: "<b>Hello world?</b>",
    });
 }

main()

через несколько секунд вываливается несколько ошибок
