Bad Request Error Sending from Nodejs - Raw Message Missing header info - node.js

Question

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: 'dhook#fullonconsulting.com',
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

Answer 1

I was not passing the info correctly from my front-end form which was causing the issue.

You can try expanding the response.body object and look for the error messages along with the help messages that you are getting.
