Key from to doc count – How to solve this Elasticsearch error

Briefly, this error occurs when Elasticsearch is trying to retrieve data from a specific range (from-to) or count documents (doccount) but the key or field specified doesn’t exist or is incorrect. To resolve this, ensure that the field you’re querying exists in your index. If it does, check for typos or case sensitivity issues in your query. Also, verify that your data type matches the query type. For instance, you can’t use a range query on a text field. Lastly, if you’re using an aggregation, ensure that the field you’re aggregating on is not analyzed.

This guide will help you check for common problems that cause the log ” Key [{}]; from [{}]; to [{}]; doc_count [{}] ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: aggregations.

Log Context

Log “Key [{}]; from [{}]; to [{}]; doc_count [{}]” classname is iprange-aggregation.asciidoc.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

     String key = entry.getKeyAsString();            // Ip range as key
    String fromAsString = entry.getFromAsString();  // Ip bucket from as a String
    String toAsString = entry.getToAsString();      // Ip bucket to as a String
    long docCount = entry.getDocCount();            // Doc count

    logger.info("key [{}]; from [{}]; to [{}]; doc_count [{}]"; key; fromAsString; toAsString; docCount);
}
--------------------------------------------------

This will basically produce for the first example:
