> The PutElasticsearchJson processor can extract the Elasticsearch index name,
> document ID, and @timestamp value from a field within each document (via the
> Index Field, Identifier Field, and Timestamp Field properties added in
> NIFI-15985). Today those properties only match a top-level field name, so a
> document that carries this information in a nested object cannot be used as a
> source. For example, with a document like: \{ "@metadata": { "index":
> "logs-2026", "id": "abc-123" }, "message": "..." } setting Index Field to
> "@metadata/index" currently finds nothing (there is no top-level key
> literally named "@metadata/index") and silently falls back to the configured
> Index property. Nesting routing/metadata under an envelope such as
> "@metadata" is a common pattern (e.g. coming from Logstash), so users have no
> way to get the index/id/timestamp from it.
