Hey @jasoniharris thanks for the contribution!

Apropos build - I think something funny is going on in actions. I will re-run tomorrow and see if it self-resolves, else we can dive deeper. Doesn't seem to be related to your change.

Deploying with SAM:

./gradlew build
sam deploy --guided

I end up with:

curl https://ggb2st3t75.execute-api.eu-central-1.amazonaws.com/Prod/hello/ 
{"message": "Internal server error"}

and a stacktrace in the logs:

2023/10/03/[$LATEST]b0a62771de7d455ebe580d40e170ffb1 2023-10-03T16:39:15.982000 Class not found: helloworld.App: java.lang.ClassNotFoundException

Have I missed something?

I think we need to update the instructions. The correct way with SAM should be sam build && sam deploy --guided

[scottgerring]

This is good for me. The E2E tests fail because of the security config, not an issue with the PR. @jeromevdl do you want to have a skim before we merge to make sure i've not missed anything funny given recent repo structure issues?

[jeromevdl]

a few minor things and we're good

[AlexeySoshin]

Should be removed
