ERROR: Cannot find default log service

I’m trying to connect liquibase to an existing CDI servlet.
I am using liquibase.version=4.31.0, WebSphere Application Server 24.0.0.12
As recommended I implemented the class LiquibaseProducer.
After starting, the method createConfig() is called and after then follows following error:

2025-04-24 14:18:50,683 ERROR [Default Executor-thread-2] liquibase.integration - Cannot find default log service
