Without more of your code, the error stack, or what your are trying to accomplish - this is just a shot in the dark for a solution.

It appears you are not formatting an email options parameter properly, so nodemailer is complaining that it doesn’t have any properly formatted addresses to send to. What does your Email.send() options object look like? Ensure that:

// Server code
import { Email } from 'meteor/email';

const sendEmail = function() {
  const options = {
    to: 'to@example.com', // String or array of strings ['You <you@example.com>', 'another@example.com']
    from: 'from@example.com', // String
    subject: 'Regarding this email',
    text: 'Hello World',
  }
  Email.send(options);
}

sendEmail();
