Docker push "Missing image name"-error when pushing to GCP Artifact Registry from Github Actions

I am running the google-github-actions/deploy-cloudrun Action on Github, which fails when trying to push a docker image to Artifact Registry.

1. I authenticate through an identity pool
2. The docker image builds successfully
3. However, pushing the image to Google Artifact Registry fails with name invalid: Missing image name. Pushes should be of the form docker push HOST-NAME/PROJECT-ID/REPOSITORY/IMAGE

Github action YML

# Authenticate Docker to Google Cloud Artifact Registry
  - name: Docker Auth
    id: docker-auth
    uses: 'docker/login-action@v1'
    with:
      username: 'oauth2accesstoken'
      password: '${{ steps.auth.outputs.access_token }}'
      registry: '${{ env.GAR_LOCATION }}-docker.pkg.dev'

  - name: Build and Push Container
    run: |-
      docker build -t "${{ env.GAR_LOCATION }}-docker.pkg.dev/${{ env.PROJECT_ID }}/${{ env.SERVICE }}:${{ github.sha }}" .
      docker push "${{ env.GAR_LOCATION }}-docker.pkg.dev/${{ env.PROJECT_ID }}/${{ env.SERVICE }}:${{ github.sha }}"

Log output

I do have Artifact Registry enabled, and created repository with the path us-central1-docker.pkg.dev/[my-project]/github-actions

The IAM role has following permissions

• Artifact Registry Administrator
• Cloud Run Admin
• Service Account User

I am out of ideas why to the authenticated docker it appears that the registry doesn't exist.
