Rebuild failure - skipping "after_assets_precompile" section of app.yml

As a test, I moved the after_assets_precompile commands to the custom command section.

run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  ## command to password protect the website during work. remove for production.
  - exec:
      cd: $home
      cmd:
        - echo "Beginning of precompile commands"
        - sudo -E -u discourse bundle exec rake s3:upload_assets
        - sudo -E -u discourse bundle exec rake s3:expire_missing_assets
  - exec: echo "End of custom commands"

The commands worked without any issues. This rules out environmental access or security issues.

The launcher process is skipping the after_assets_precompile code during the rebuild.

Any one have a clue?
