Simple mail send is not working with node lib

[mahamudml]

Issue Summary

I'm using simple example to send email, as mentioned in https://www.npmjs.com/package/@sendgrid/mail
I'm getting weird response asking for template_id or content.

Code Snippet

const sendgrid = require('@sendgrid/mail')
sendgrid.setApiKey(process.env.SENDGRID_API_KEY)

const sendEmail = (options) => {
  return sendgrid.send({
    from: options.from,
    to: options.to,
    subject: options.subject,
    text: options.body,
    html: options.body,
  }).then((response) => {
    console.log(response[0].statusCode)
    console.log(response[0].headers)
  }).catch((error) => {
    console.error(JSON.stringify(error))
  })
}
