rails user

I agree. I'd like to know if JQ UI is still a good choice for 2022 and how it fits into the current FE ecosystem.

This will happen with ES on your local machine bc the secutiry features actually are not enabled. You can ignore this for local dev. In prod, something like a hosted ES instance on Heroku will have default security settings. I silenced this warning locally and in CI with "xpack.security.enabled: false"
