tag prefix not working

[Jordan886]

I'm transitioning my pipelines to oci-build-task and registry-image resource, unfortunately i had a problem with the second, so for now i'm keeping docker-image for pushing to the registry.

my pipeline is very simple and look like this

resources:

  - name: ((project))-docker-image
    type: docker-image
    icon: docker
    source:
      repository: ((registry_base_url))/((project))
      username: ((user))
      password: ((registry_token))

  - name: ((project))-stage.git
    type: git
    icon: gitlab
    check_every: 10s
    source:
      uri: ((git_repo_url))
      branch: staging
      username: ((user))
      password: ((pwd))

jobs:

  - name: Build-and-push-((project))-stage
    public: true
    plan:
      - get: ((project))-stage.git
        trigger: true
      # Build the image with oci-container
      - task: build-image
        privileged: true
        config:
          platform: linux
          image_resource:
            type: registry-image
            source:
              repository: vito/oci-build-task
          params:
            CONTEXT: ((project))-stage.git
          inputs:
            - name: ((project))-stage.git
          outputs:
            - name: image
          caches:
            - path: cache
          run:
            path: build
      # Upload the image with the tag latest and git commit
      - put: ((project))-docker-image
        params:
          import_file: image/image.tar
          tag_prefix: ci
          additional_tags: ((project))-stage.git/.git/ref
          tag_as_latest: true
        get_params:
          skip_download: true

basically i neeed to push to the registry a tag ci-"commit hash", the problem is that everything i write in pipeline as prefix gets ignored and image is only tagged with the commit ref.
