service_ensure_stopped use service_check_running to check is a service is running or not.
service_check_running_ps checks if the service is running, and if it is, it returns a success class, if it is not, it returns an error class

So when the service is stopped (which is the expected status), service_check_running_ps outputs an error message

R: [ERROR] Promise could not be repaired, error encountered: Check if the service SERVICENAME is started using ps
