Before you begin reading this guide, we recommend you try running the Elasticsearch Error Check-Up which analyzes 2 JSON files to detect many configuration errors.

Briefly, this error occurs when Elasticsearch is trying to update the mapping for an index, but the update is taking too long. This can happen if the mapping is very complex or if there is a large volume of data being processed. To resolve this issue, you can try increasing the timeout value or simplifying the mapping.
