Briefly, this error occurs when Elasticsearch is attempting to remove a data stream that no longer exists or is in use. This could be due to a misconfiguration or an incorrect command. To resolve this issue, you can verify the existence of the data stream before attempting to remove it. If it doesn’t exist, no action is needed. If it does exist but is in use, ensure all operations on the data stream have been completed or stopped before removal. Also, check your commands and configurations for any errors or inconsistencies.

            Metadata.Builder metadata = Metadata.builder(currentState.metadata());
            for (String ds : dataStreamsToRemove) {
      "removing data stream [{}]"; ds);
            currentState = ClusterState.builder(currentState).metadata(metadata).build();
            return deleteIndexService.deleteIndices(currentState; backingIndicesToRemove);
