trying https://github.com/serverless/examples/tree/master/aws-node-twilio-send-text-message
but the README only describes how to setup the serverless portion
yet the nodeJS stuff is quite broken or not obviously documented

Hello @copremesis 👋 Thanks for reporting. Unfortunately, that example is quite outdated, we'd be more than happy to accept a contribution that updates it 🙌
