I have a really confusing problem when I use Quarkus and Keycloak in docker compose. When I set the environment variables to override the dev configuration aka quarkus.oidc.auth-server-url and the quarkus.datasource.jdbc.url and then try to run the docker-compose file an error message appears. It says that my auth-server-url is not correct, but I do not see an typo or a mistake in my auth-server-url.
Error message:
