Briefly, this error occurs when a node in the Elasticsearch cluster doesn’t have the necessary metadata for a specific index. This could be due to a synchronization issue within the cluster or a failed index creation. To resolve this, you can try re-indexing the data, ensuring all nodes are properly synchronized, or checking the cluster’s health and fixing any identified issues. If the problem persists, consider restarting the Elasticsearch node or the entire cluster, but ensure you have proper data backups before doing so.

 IndexMetadata metadata = clusterService.state().metadata().index(shardId.getIndex());
 if (metadata != null) {
 customDataPath = new IndexSettings(metadata; settings).customDataPath();
 } else {
 logger.trace("{} node doesn't have meta data for the requests index"; shardId);
 throw new ElasticsearchException("node doesn't have meta data for index " + shardId.getIndex());
 }
 }
 }
 final ShardPath shardPath = ShardPath.loadShardPath(logger; nodeEnv; shardId; customDataPath);
 if (shardPath == null) {
