Packetbeat Processors - Dropping fields from nested objects in an array

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

Could you please share you whole configuration? Your configuration seems correct, but you might have some indentation error.

Sure. here is my entire processors section of the YAML file.

processors:
    - drop_event:
        when:
          not:
            equals:
              dns.response_code: "NOERROR"
    - include_fields:
        fields:
          - dns.question.name
          - dns.question.type
          - dns.answers
          - dns.answers_count
          - dns.resolved_ip
          - dns.txt_answers
    - drop_fields:
        fields:
          - dns.answers.name
    - copy_fields:
        fields:
          - from: dns.answers.data
            to: dns.txt_answers
        ignore_missing: true
        fail_on_error: false

In addition, if you see I tried copying the "dns.answers.data" field to a separate field (like what is done in the dns.resolved_ip field), and this doesn't seem to work either.
The field configuration in the mapping is:

setup.template.overwrite: true
setup.template.append_fields:
- name: dns.txt_answers
  type: text
  level: extended

Also, here is the error I get:
Failed to copy fields in copy_fields processor: could not fetch value for key: dns.answers.data, Error: expected map but type is common.MapStr

I think it might have to do with the following issue:
