Besides the changes metioned on issue 394, for accounts created after October 1, 2024, AWS now requires the use of Launch Templates to create an environment with Auto Scaling. This is required to follow along the tutorial when deploying with Beanstalk.
I had to spend a few hours figuring out how to do this, since I'm new to AWS.
It'd be great to update the tutorial with instructions on how to do this considering this new requirement.
