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 encounters a problem while trying to parse a field in the index mapping. The mapping defines the fields and data types of a document index. This error typically occurs when there is a mismatch between the data type defined in the mapping and the actual data type of the indexed data. To resolve this issue, you should check the mapping and ensure that the data type of the field in the mapping matches the actual data type of the indexed data.

To easily locate the root cause and resolve this issue try AutoOps for Elasticsearch & OpenSearch. It diagnoses problems by analyzing hundreds of metrics collected by a lightweight agent and offers guidance for resolving them.

This guide will help you check for common problems that cause the log ” object mapping for ” + mapper.name() + ” tried to parse field ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: mapping and index.
