Sounds a known issue filed a redmine issue -> Bug #32556: CV Promotion/Composite cv publish failed with NoMethodError: undefined method `get_status' for nil:NilClass - Katello - Foreman
Try the following workaround

  1. Change the context to “Any Location”
  2. Publish and promote the CV

Many thanks - that was is it - the workaround worked perfectly (we have two locations in our katello setup)
