We’re migrating our Java 17 service from Spring Boot 2 to Spring Boot 3 and thus Hibernate 5 to Hibernate 6. I anonymized the examples below by using an animal example.

We are trying to upgrade our Spring Boot version from 2.4.2 to 3.3.1. (We are also upgrading the project’s JDK version from 11 to 21.)
Following are the dependencies in the project

I have a Spring Boot project that works fine on Windows, but on Fedora with PostgreSQL running in a Podman container, I get Unable to determine Dialect without JDBC metadata (please set 'jakarta.persistence.jdbc.url' for common cases or 'hibernate.dialect' when a custom Dialect implementation must be provided). I have added that configuration, but continue to get the same message. My code can be found here. What am I missing?
