Briefly, this error occurs when Elasticsearch is unable to fetch the checkpointing information for a specific data transform. This could be due to issues like incorrect transform ID, insufficient permissions, or network connectivity problems. To resolve this, ensure the transform ID is correct and the user has the necessary permissions. Also, check the network connectivity between the nodes. If the issue persists, consider restarting the Elasticsearch cluster or reindexing the data.

Log Context
Log “Failed to retrieve checkpointing info for transform [” + transform.getId() + “]” classname is TransportGetTransformStatsAction.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :
transform.getId();
transform.getTransformState().getCheckpoint();
transform.getTransformState().getPosition();
transform.getTransformState().getProgress();
ActionListener.wrap(infoBuilder -> listener.onResponse(infoBuilder.build()); e -> {
logger.warn("Failed to retrieve checkpointing info for transform [" + transform.getId() + "]"; e);
listener.onResponse(TransformCheckpointingInfo.EMPTY);
})
);
}
