Bad Request Error Sending from Nodejs – Raw Message Missing header info – Nginx

I am trying to send an email using nodejs on a vercel host.

I am getting a bad request using the sendgrid/mail api. It looks as though it is not creating the header info in the request to Sendgrid.

When I dump the message, is it just the json info i am sending.

Here is the code i am using.

const sgMail = require('@sendgrid/mail')

const SENDGRID_API_KEY = process.env.SENDGRID_API_KEY;

export default function (req, res) {

    const mailData = {
        from: '[email protected]',
        to: req.body.email,
        subject: 'Message to Full On Consulting',
        text: req.body.message,
        html: '<div>'+req.body.message+'</div>'
    }
    const {
      classes: {
        Mail,
      },
    } = require('@sendgrid/helpers');
    const mail = Mail.create(mailData);
    const body = mail.toJSON();
    console.log("======================================== ");
    console.log("RAW BODY: " + JSON.stringify(body));
    console.log("======================================== ");

    sendMail(mailData)
    .then((result) => {
            console.log('Email sent...', result);
            res.status(200).json({ status: 'SUCCESS' })
        })
    .catch((error) => console.log('Error ... ' + error.message));
}

async function sendMail(mailData) {
  try {

    var promise = new Promise( (resolve, reject) => {

      sgMail.setApiKey(SENDGRID_API_KEY)

      const msg = {
        to: mailData.to, // Change to your recipient
        from: mailData.from, // Change to your verified sender
        subject: mailData.subject,
        text: mailData.text,
        html: mailData.html,
      }
      console.log("API KEY: " + SENDGRID_API_KEY);
      console.log(JSON.stringify(msg));

      sgMail
        .send(msg)
        .then(() => {
          console.log('Email sent');
        })
        .catch((error) => {
          console.error(error);
          console.log('RECEIVED ERROR')
        })
    });

     //promise.then( result => {
     // console.log("PRomise Success ...");
     //}, function(error) {
     // console.log("Promise Failure...");
     //});

  } catch (error) {
        console.log("CATCH ERROR: " + error)
        return error;
  }
}

Here is the Error
