Failed to update mappings on audit index – How to solve this Elasticsearch error

Opster Team

Aug-23, Version: 6.8-6.8

Briefly, this error occurs when Elasticsearch is unable to update the schema (mappings) of an index, in this case, the audit index. This could be due to a variety of reasons such as incorrect mapping format, insufficient permissions, or a conflict with existing mappings. To resolve this issue, you can check the mapping syntax for errors, ensure the user has the correct permissions to update mappings, or delete and recreate the index with the correct mappings. If there’s a conflict with existing mappings, you may need to reindex your data with the correct mappings.

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.
