SendGrid Azure Issue - node.js

Question

I'm trying to send an email with my Node JS app on Azure and get this error:
TypeError: sendgrid.Email is not a constructor
Here is my code. I used the documentation from Microsoft (https://learn.microsoft.com/en-us/azure/store-sendgrid-nodejs-how-to-send-email).
var sendgrid = require('sendgrid')('SendGrid User ID', 'SendGrid password');
function createEmail() {
console.log('CREATE EMAIL');
var emailToSend = new sendgrid.Email({
to: example#example.com,
from: 'example#example.com',
subject: 'Subject',
text: 'some text';
});
sendEmail(emailToSend);
}
function sendEmail(email) {
console.log('SEND EMAIL');
sendgrid.send(email, function (err, json) {
if (err) {
return console.error(err);
}
});
}

As #David Tansey mentioned, the SendGrid team added a breaking change to support the v3 Web API since v3.0.0. Here is a working code example with the latest version (v5.1.2).
var helper = require('sendgrid').mail;
var fromEmail = new helper.Email('test#example.com');
var toEmail = new helper.Email('test#example.com');
var subject = 'Sending with SendGrid is Fun';
var content = new helper.Content('text/plain', 'and easy to do anywhere, even with Node.js');
var mail = new helper.Mail(fromEmail, subject, toEmail, content);
var sg = require('sendgrid')(process.env.SENDGRID_API_KEY);
var request = sg.emptyRequest({
method: 'POST',
path: '/v3/mail/send',
body: mail.toJSON()
});
sg.API(request, function (error, response) {
if (error) {
console.log('Error response received');
}
console.log(response.statusCode);
console.log(response.body);
console.log(response.headers);
});
However, if you want your provided code run smoothly, you'll need to revert the version to 2.0.0.
