When I use a transactional template , this ignore the recipient

[juanOlivasG]

Issue Summary

When using the @sendgrid/mail client for Node, when I try to use a transactional template it does not work, it sends the email to Sendgrid and response status 202 but I never receive the email, when I check the SendGrid console the email is there with status not delivered when I test the template with SendGrid portal it works I am able to send me test emails.

When I send an email without a transactional template it works well, the problem is when I try to use the template it ignores the recipient.

//template code
html>
head>
title></title>
/head>
body>
div data-role="module-unsubscribe" class="module" role="module" data-type="unsubscribe" style="color:#444444; font-size:12px; line-height:20px; padding:16px 16px 16px 16px; text-align:Center;" data-muid="4e838cf3-9892-4a6d-94d6-170e474d21e5">
        
        You've been assigned to {{ticketType}} #{{ticketNumber}} on the {{projectName}} project.
/div>
/body>
/html>

//node code
const sgMail = require('@sendgrid/mail')
sgMail.setApiKey(process.env.SENDGRID_KEY)
sgMail.setSubstitutionWrappers('{{', '}}')

const dispatchEmail=async(email,sendgrid_from,templateId,substitutions)=>{
  const projectName = 'Project Foo';
  const ticketNumber = 1234;
  const msg = {
    personalizations: [{
      to: [{
        email: email,
        name: 'myself',
      }],
    }],
    from: {
      email: sendgrid_from,
      name: 'myself',
    },
    templateId:templateId,
    dynamic_template_data: {
      ticketNumber,
      projectName,
      ticketType: 'bar',
    },
  };

  await sgMail.send(msg).then(([response, body]) => {
    console.log(response);
    console.log(body);
  }).catch(err => console.log(err));
}

exports.dispatchEmail=dispatchEmail
