Orb is stated to be unused

[BrentWilkins]

I roughly copy-pasted the following code from this example.

version: 2.1
orbs:
  aws-cli: circleci/[email protected]
  aws-ecr: circleci/[email protected]
jobs:
  build-test-then-push-with-buildx:
    machine:
      image: ubuntu-2204:2023.07.2
    steps:
      - aws-ecr/build_and_push_image:
          attach_workspace: true
          auth:
            - aws-cli/setup:
                role_arn: arn:aws:iam::123456789012
          create_repo: true
          dockerfile: Dockerfile
          path: workspace
          platform: linux/amd64
          push_image: false
          region: us-west-2
          repo: my-sample-repo
          tag: sampleTag
          workspace_root: .

workflows:
  build-and-test:
    jobs:
      - build-test-then-push-with-buildx

aws-cli: circleci/[email protected] has the yellow squiggly underline. It expands to this:

Orb is unused cci-language-server
https://circleci.com/docs/creating-orbs#semantic-versioning-in-orbs

An orb to depend on and its semver range, or volatile for the most recent release.

CircleCI config.yml
https://circleci.com/docs/creating-orbs#semantic-versioning-in-orbs

An orb to depend on and its semver range, or volatile for the most recent release.

What is it called when we use it in the auth section below that? In my actual project I don't get the unused error, but I get an undefined error where I use it.

Thanks for bringing this issue to our attention! It seems we do not consider an orb as used when its steps are used as a parameter to another step. Looking into this.

In my actual project I don't get the unused error, but I get an undefined error where I use it.

I'm not sure I actually understand. Could you explain what you mean by "an undefined error where I use it"? Feel free to share screenshots or code snippets.
