No field mapping can be found for the field with name – How to solve this Elasticsearch error

Opster Team

July-20, Version: 1.7-8.0

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 message typically occurs when Elasticsearch is unable to find a field mapping for a field that is being queried or indexed. This can occur when the field has not been explicitly mapped in the index, or when the field mapping has been defined incorrectly. To resolve this issue, ensure that the field is properly mapped in the index with the correct data type and any necessary settings. If the field has not been explicitly mapped, Elasticsearch may be able to automatically infer the mapping based on the data being indexed. Alternatively, the field can be excluded from the query or indexing operation.

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.
