Packetbeat - How to drop_fields from nested object

Question

I recently started working with Packetbeat.

For my use-case, I only need some specific fields (to the point where if I could I would completely rewrite the mapping, but am leaving that as a last resort).

I tried removing some of the fields from the "dns.answers" array of objects, but what I did doesn't seem to have any effect:

    - include_fields:
        fields:
          - dns.question.name
          - dns.question.type
          - dns.answers
          - dns.answers_count
          - dns.resolved_ip
    - drop_fields:
        fields:
          - dns.answers.name

In addition, I also tried including only the fields I want but that didn't seem to work either, e.g:

- include_fields:
        fields:
          - dns.question.name
          - dns.question.type
          - dns.answers.data
          - dns.answers_count
          - dns.resolved_ip

Any ideas? If rewriting the template/mapping of the index is the best choice, or perhaps using the Ingest Node Pipelines is a better approach, I'd love to hear it.

Thanks
