@sendgrid/mail not sending email after upgrade

[saniyusuf]

We use Sendgrid in a NodeJS environment via the MongoDB Atlas Function environment. We were using version 7.7.0 and all worked as emails were sent.

We recently created the same exact function with the latest version (8.1.3), and the email didn't send, citing TypeError with the message "Not a function".

We downgraded to 7.7.0, and the email was sent. This shows something is definitely wrong with the new version of the client.
