Transform has no consumers

[DVVolkov]

Hi!
That my vector.yaml conf file

sources:
  docker_app_test:
    type: docker_logs
    auto_partial_merge: true
    include_containers:
      - mynginx

transforms:
  formatting_logs:
    type: remap
    inputs:
      - docker_app_test
    source: parse_nginx_log!(
      .message,
      "combined",
      )

sinks:
  loki:
    type: loki
    inputs:
      - docker_app_test
    endpoint: http://10.10.10.10:3100
    path: /loki/api/v1/push
    encoding:
      codec: "json"
      json:
        pretty: true
    labels:
      mynginx: docker_app_test

When i run vector i get this warning: WARN "vector::config::loading: Transform "formatting_logs" has no consumers"
I look at what came to me in loki, and the log comes in the format:

{
  "container_created_at": "2024-12-13T11:18:19.516635042Z",
  "container_id": "aab04b98e1bd6f873d4b54839910e9092922fe6e7834f28e6c2f7cd7c7f98f59",

  },

  "source_type": "docker_logs",
  "stream": "stdout"
}

Well, i try a simpler function and want to remove labels, i don't need them

Change vector.yaml transforms.source section

transforms:
  formatting_logs:
    type: remap
    inputs:
      - docker_app_test
    source: del(.label)

And even that doesn't work. I still see WARN "vector::config::loading: Transform "formatting_logs" has no consumers"

I can't understand why vector doesn't see consumers, what am I doing wrong?
Thanks for any help!

In sinks.inputs I re-entered unformatted data. It took me half a day, be careful, don't be like me :)
