Briefly, this error occurs when the Elasticsearch REST API receives a request that has been tampered with or malformed. This could be due to incorrect syntax, invalid parameters, or unauthorized modifications. To resolve this issue, you can: 1) Check the syntax of your request to ensure it’s correct. 2) Verify the parameters in your request are valid and in the correct format. 3) Ensure the request hasn’t been modified by unauthorized users or processes. 4) If you’re using a client library to send requests, ensure it’s up-to-date and compatible with your Elasticsearch version.
