This could be due to incorrect syntax, invalid data format, or a malformed request. To resolve this issue, you can: 1) Check and correct the syntax of your HTTP request. 2) Validate the data format you’re using against Elasticsearch’s expected format. 3) Ensure the request is properly formed and doesn’t contain any invalid or unsupported parameters.
