Error undefined method '#ip' for NilClass when trying to generate "Ansible - Ansible Inventory" report from a Red Hat Satellite 6.16

Issue

• Soon after upgrading to Red Hat Satellite 6.16, The inventory plugin redhat.satellite.foreman has stopped working with the reports_api :

  # cat my.foreman.yml
  plugin: redhat.satellite.foreman
  
  url: https://satellite616.lab.example.com
  user: admin
  password: ******
  use_reports_api: true
  
  
  # ansible-inventory -i my.foreman.yml --list 
  [WARNING]: Failed to use Reports API, falling back to Hosts API: Error receiving inventory report from foreman. Please check foreman logs!
  {
      "_meta": {
  ...
  

• It's not possible to generate a report from Ansible - Ansible Inventory report template as it fails with error undefined method '#ip' for NilClass, as well.
