Preview & Deployment URL outputs are null when vercel build fails

[zognotadog]

When the vercel build fails, the preview and deploy outputs are not provided. We are trying to log the build logs in the PR if this happens. We cannot do this without the preview-url. Please can it be change to still output these on failure?

  # Deploy using the build files
  - name: Deploy to Vercel
    id: vercel-deploy
    uses: amondnet/vercel-action@v25 # Deploy to Vercel
    with:
      github-token: ${{ secrets.VERCEL_GITHUB_TOKEN }}  # Optional
      vercel-token: ${{ secrets.VERCEL_TOKEN }}  # Required

      vercel-project-id: ${{ vars.VERCEL_PROJECT_ID }}  # Required 
      alias-domains: |
        ${{ 
          github.ref == 'refs/heads/main' && 'app.app.co.uk' || 
          github.ref == 'refs/heads/dev' && 'dev.app.co.uk'
        }}
      github-comment: true
  
  - name: Log Deployment Outputs
    if: failure()
    run: |
      echo "Deployment URL: ${{ steps.vercel-deploy.outputs.deployment-url }}"
      echo "Preview URL: ${{ steps.vercel-deploy.outputs.preview-url }}"`

Kind same issue here. The deploy is being done but when trying to log the step.[VERCEL_ACTION_STEP_ID].outputs.preview-url nothing is being shown.

This is avoiding our tests to run over the preview in our CI workflow after preview deployment
