                    logger.info("updating index lifecycle policy [{}]"; request.getPolicy().getName());
            IndexLifecycleMetadata newMetadata = new IndexLifecycleMetadata(newPolicies; currentILMMode(currentState));
            stateBuilder.metadata(Metadata.builder(currentState.getMetadata()).putCustom(IndexLifecycleMetadata.TYPE; newMetadata).build());
