Briefly, this error occurs when an invalid index setting is detected by Elasticsearch. The setting ‘archiving’ is not recognized by Elasticsearch, hence it is ignored. To resolve this issue, you should review your index settings and remove or correct the invalid setting. Ensure that all settings are spelled correctly and are supported by your version of Elasticsearch. If ‘archiving’ is a custom setting, make sure it is implemented correctly. Also, always validate your settings before applying them to avoid such errors.
