Error updating template – How to solve this Elasticsearch error

Opster Team

Aug-23, Version: 6.8-8.2

Briefly, this error occurs when there’s an issue updating an index template in Elasticsearch. This could be due to incorrect syntax in the template, insufficient permissions, or a conflict with an existing template. To resolve this, ensure the template syntax is correct and you have the necessary permissions to update templates. If a template with the same name exists, consider renaming the new template or deleting the old one. Also, check the Elasticsearch version as some template features may not be supported in older versions.

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.

                    logger.warn(new ParameterizedMessage("Error updating template [{}]"; change.getKey()); e);
                    tryFinishUpgrade(anyUpgradeFailed);
                }
            });
        }
