elasticsearch_parse_exception: elasticsearch_parse_exception

What does it mean?

Elasticsearch hit a generic parsing error while parsing the request body (JSON query, settings or configuration). The request does not structurally match the expected format.

Why does it happen?

Malformed/invalid JSON (missing comma, unclosed bracket), misplaced fields, unexpected value types (e.g. text where a number is expected), or an invalid time/range expression. Incorrect nesting of a DSL query also produces this exception.

How to fix it

Run the request body through a JSON validator; check brackets, quotes and commas. Check against the Elasticsearch DSL documentation that fields are in the right place and of the right type. Use the position/field hint in the error message to fix the problematic part. If you use a client library, make sure serialization produces valid JSON.
