I've got a custom Amplify Lambda function, and I want to get the value of ${env} in it; for example values of 'dev', 'test', 'prod' for my team environments. How do I do this in "the Amplify way"?

I've done a bunch of googling, and there are answers from 2019 that involve hacking the CloudFormation templates, but I'm not sure if that applies anymore in 2024...

Hi @foggy prism are you using Amplify gen1 or gen2?

If its gen2 this https://docs.amplify.aws/react/build-a-backend/functions/environment-variables-and-secrets/ works fine, its working for me on my current project.

To answer my own question: There is an environment variable passed to every Amplify Lambda function called ENV. So all you have to do in your code is access process.env.ENV.
