@xlisachan @LZoog You mind taking a look at this when you get a moment? I believe these are the right configs for mjml render but I am not super familiar with it.

Yay! 🎉

I only remember the warning would come up when I ran yarn test test/local/senders/emails.ts in fxa-auth-server, so I pulled your branch, ran the test, and the warning is gone!! If there is another place to check, please let me know. 👀

Thanks for fixing this, Vijay!
