Drop irrelevant filebeat docker metadata not working

[Chma]

I am using filebeat to ship container logs to ELK. I have way too many metadata that I don't need.
container.id, container.name, conatiner.labels, container.image and so on. The only one I need her is container.name, so I am trying to drop the rest.

This is my configuration file, but what had worked for dropping the host meta isn't working for dropping the docker metadata. Am I missing something?

filebeat.inputs:
- type: filestream
  id: my-filestream-id
  enabled: true
  paths:
    - /home/logs/**/*.log
- type: container
  enable: true
  paths: 
    - "/var/lib/docker/containers/*/*.log"
filebeat.config.modules:
  path: /etc/filebeat/modules.d/*.yml
  reload.enabled: false
filebeat.autodiscover:
  providers:
    - type: docker
      hints.enabled: true
processors:
  - add_host_metadata:
      when.not.contains.tags: forwarded
  - add_cloud_metadata: ~
  - add_docker_metadata: 
      host: "unix:///var/run/docker.sock"
  - drop_fields:
      fields: ["container.id", "container.labels", "container.image"]
  - decode_json_fields:
      fields: ["message"]
      target: "json"
      overwrite_keys: true
  - drop_fields:
        fields: ["agent", "cloud", "ecs", "host", "input", "tags"
        ignore_missing: true
output.logstash:
  hosts: ["${elasticip}:5044"]
