Briefly, this error occurs when Elasticsearch receives a request containing a field or parameter that it doesn’t recognize or support. This could be due to a typo, incorrect syntax, or usage of a feature not available in the current version of Elasticsearch. To resolve this issue, you should first verify the field or parameter causing the error. Ensure it’s spelled correctly and is supported in your Elasticsearch version. If the error persists, check your request syntax or consider upgrading your Elasticsearch if the feature is not supported in your current version.
