When starting the stack with docker compose, it fails because:

✘ genai-service Error pull access denied for springcommunity/spring-petclinic-genai-service, repository does not exist or may require 'docker login' 1.0s
Error response from daemon: pull access denied for springcommunity/spring-petclinic-genai-service, repository does not exist or may require 'docker login'

It seems that the Docker image is not published to the springcommunity repository. As a workaround, I disabled this GenAI service from the docker compose, and the whole was started as expected.
