Failed to retrieve mapping version for recreating – How to solve this Elasticsearch error

Opster Team

Aug-23, Version: 6.8-8.2

Briefly, this error occurs when Elasticsearch is unable to fetch the mapping version needed to recreate an index. This could be due to a network issue, a node failure, or the index being deleted. To resolve this, you can try restarting the Elasticsearch cluster, ensuring all nodes are properly connected. If the index was deleted, you may need to recreate it. Also, check your cluster health and ensure it’s green. If the issue persists, you might need to check your Elasticsearch logs for more detailed error information.

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.
