I was taking a look to the logs available at  https://oil-jenkins.canonical.com/artifacts/c26f6331-7387-4938-8921-9c09302d8087/generated/generated/openstack/juju-crashdump-openstack-2022-10-25-14.15.19.tar.gz , and the error posted is misleading, this is being printed before config-changed has generated the configuration, after those errors it can be seen how octavia-worker started running successfully
