Briefly, this error occurs when there’s an issue with the aggregation query in Elasticsearch. The “doccount” is a key part of the response from an aggregation query, and if it’s not correctly handled, it can lead to this error. To resolve this issue, you can check the structure of your aggregation query to ensure it’s correct. Also, ensure that the field you’re aggregating on exists in your documents and is of the correct type. Lastly, check if the Elasticsearch version you’re using supports the features you’re trying to use in your query.

Log Context

Log “Key [{}]; point {}; doc_count [{}]” classname is geohashgrid-aggregation.asciidoc.

 for (GeoHashGrid.Bucket entry : agg.getBuckets()) {
    String keyAsString = entry.getKeyAsString(); // key as String
    GeoPoint key = (GeoPoint) entry.getKey();    // key as geo point
    long docCount = entry.getDocCount();         // Doc count"key [{}]; point {}; doc_count [{}]"; keyAsString; key; docCount);

This will basically produce:
