I removed this because I was getting an error that -release:21 is not a valid compiler option when I ran the code. Looking at the docs: https://docs.scala-lang.org/overviews/compiler-options/ my understanding is that this is not supported for Java 21.

I tried on my local machine and it compiled successfully with -release:21 option. Did I miss anything here? (my local Java is 21.0.2-amzn)

I also got this error initially and can confirm it went away once I switched to java 21

Yeah, the docs at https://docs.scala-lang.org/overviews/compiler-options/ are unhelpful there - I've opened scala/docs.scala-lang#3009 to try to improve them!
