Getting unauthorised for github container registry

[Sabreen-Parveen]

I am using this action to scan images present in github container registry, I have set the registery-username variable to my username and have used ${{ secrets.GITHUB_TOKEN }} for my password. But when the action is running it is giving me unauthorised. To authenticate with GITHUB_TOKEN, I have followed this github doc.

My github action:

scan:
    name: 🛡️ Scan docker images
    runs-on: ubuntu-latest
    permissions:
      packages: read
      contents: read
    needs: get_images
    strategy:
      fail-fast: false
      matrix: ${{ fromJSON(needs.get_images.outputs.images) }}
    steps:
      - name: scan ghcr images
        uses: anchore/scan-action@v3
        if: ${{ startsWith( matrix.images, 'ghcr.io' ) }}
        id: scan-ghcr
        with:
         image: ${{ matrix.images }}
         fail-build: true
         severity-cutoff: critical
         output-format: json
         registry-username: sabreen-parveen
         registry-password: ${{ secrets.GITHUB_TOKEN }}

Error

Getting following warning and error message:

The same behavior.

Scan-image:
    needs: [Build-docker-Airflow]
    runs-on:
      - self-hosted
    steps:
      - name: Scan image
        uses: anchore/scan-action@v3.3.6
        with:
          image: ${{ env.repo }}/${{ secrets.DOCKER_USERNAME }}/${{ env.image_name }}:$GITHUB_RUN_NUMBER
          fail-build: false
          registry-username: ${{ secrets.DOCKER_USERNAME }}
          registry-password: ${{ secrets.DOCKER_PASSWORD }}
