Cannot invoke "org.keycloak.models.ClientModel.getRole(String)" because "realmAdminApp" is null

Hi,

I encounter a strange issue when spin-up a new KC23.0.1 container with a MariaDB backend.

2023-12-05 13:25:10,761 ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) ERROR: Failed to start server in (production) mode
2023-12-05 13:25:10,762 ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) ERROR: Cannot invoke "org.keycloak.models.ClientModel.getRole(String)" because "realmAdminApp" is null
2023-12-05 13:25:10,762 ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) For more details run the same command passing the '--verbose' option. Also you can use '--help' to see the details about the usage of the particular command.

Is this a known issue or do I miss some kind of config?

Thanks,
Tom
