No mappings found for recreating – How to solve this Elasticsearch error

Opster Team

Aug-23, Version: 6.8-8.9

Briefly, this error occurs when Elasticsearch is unable to find the mappings required to recreate an index. Mappings define the types of data in the index and how they should be stored and searched. This could be due to a missing or incorrect mapping file. To resolve this issue, you can either provide the correct mapping file or define the mappings manually using the PUT mapping API. Also, ensure that the Elasticsearch cluster has the necessary permissions to access the mapping file.

In addition we recommend you run the Elasticsearch Template Optimizer to fix problems in your data modeling.

It will analyze your templates to detect issues and improve search performance, reduce indexing bottlenecks and optimize storage utilization. The Template Optimizer is free and requires no installation.
