I have tried to use following Nodejs code and run in local machine, it is sending an email.

const API_KEY = 'YOUR_API_KEY';
const DOMAIN = 'YOUR_DOMAIN_NAME';

import formData from 'form-data';
import Mailgun from 'mailgun.js';

const mailgun = new Mailgun(formData);
const client = mailgun.client({username: 'api', key: API_KEY});

const messageData = {
from: 'Excited User me@samples.mailgun.org',
to: 'foo@example.com, bar@example.com',
subject: 'Hello',
text: 'Testing some Mailgun awesomeness!'
};

client.messages.create(DOMAIN, messageData)
.then((res) => {
console.log(res);
})
.catch((err) => {
console.error(err);
});

Can you please help here?

I am using Node-RED version: v3.1.3, Node.js version: v19.4.0
