Sendgrid status 202 node.js

Question

I receive the following error when using SendGrid. Even though i get an error the mail is still sent.

null { statusCode: 202, body: '', headers: { server: 'nginx', date: 'Wed, 05 Jul 2017 18:50:52 GMT', 'content-type': 'text/plain; charset=utf-8', 'content-length': '0', connection: 'close', 'x-message-id': 'EUkSULsjRku6bJTkTFsQ9w', 'x-frame-options': 'DENY', 'access-control-allow-origin': 'https://sendgrid.api-docs.io', 'access-control-allow-methods': 'POST', 'access-control-allow-headers': 'Authorization, Content-Type, On-behalf-of, x-sg-elas-acl', 'access-control-max-age': '600', 'x-no-cors-reason': 'https://sendgrid.com/docs/Classroom/Basics/API/cors.html' } } _http_outgoing.js:357 throw new Error('Can\'t set headers after they are sent.');

Using the following code:

var helper = require('sendgrid').mail,
  sg = require('sendgrid')('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');

  var from_email = new helper.Email('my.mail');
  var to_email = new helper.Email('my.mai');
  var subject = 'Subject';
  var content = new helper.Content('text/plain', 'test');
  var mail = new helper.Mail(from_email, subject, to_email, content);

  var request = sg.emptyRequest({
      method: 'POST',
      path: '/v3/mail/send',
      body: mail.toJSON()
  });

  sg.API(request, function(err, response) {
      console.log(err, response);
      if (!err) {
          res.send({
              message: 'An email has been sent to the provided email with further instructions.'
          });
      } else {
          return res.status(400).send({
              message: 'Failure sending email'
          });
      }
  });

How can i fix this?

A 202 is a success message, not an error. It simply means that your message was "Accepted"

Your code shouldn't be detecting any errors on any 20x response.
