To resolve this issue, you can try restarting the Elasticsearch service, checking the health of your cluster, or reviewing the transformation process for any potential issues. If the problem persists, consider checking the Elasticsearch logs for more detailed error information.

Log Context

Log “[{}] attempt to fail transform with reason [{}] while it was stopping.” classname is
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

            // If the indexer is `STOPPING` this means that `TransformTask#stop` was called previously; but something caused
            // the indexer to fail. Since `ClientTransformIndexer#doSaveState` will persist the state to the index once the indexer stops;
            // it is probably best to NOT change the internal state of the task and allow the normal stopping logic to continue.
            if (getIndexer() != null && getIndexer().getState() == IndexerState.STOPPING) {
      "[{}] attempt to fail transform with reason [{}] while it was stopping."; getTransformId(); reason);
            // If we are stopped; this means that between the failure occurring and being handled; somebody called stop
            // We should just allow that stop to continue
