Hi, thanks.

I am not sure, I have not tried with Aurora serverless. But it is hard to troubleshoot based on only that error message. I guess you could try to create a database on that instance named "keycloak" before you connect. And then try to run the keycloak service. Would recommend to try it from a local docker-compose file with connection details to your database (just provide the same environment variables as in the task definition), that way troubleshooting should be way faster and you can check out the keycloak log locally (using docker-compose logs for instance). Good luck!
