Foreman Ansible role on CentOS 8

Support
1

Problem:
Satellite : Ansible role cannot run on CentOS 8
Expected outcome:

Foreman and Proxy versions:
foreman-1.22.0.36-1.el7sat.noarch

Foreman and Proxy plugin versions:
foreman-proxy-1.22.0.3-1.el7sat.noarch
foreman-proxy-content-3.12.0-3.el7sat.noarch

Distribution and version:
satellite-6.6.2-1.el7sat.noarch

Other relevant data:

By default, the ansible role will start with debugging and print out all foreman parameters.
—
- hosts: all
pre_tasks:
- name: Display all parameters known for the Foreman host
debug:
var: foreman
roles:
<%- if @host.all_ansible_roles.present? -%>
<%= @host.all_ansible_roles.map { |role| " - #{role.name.strip}" }.join("\n") %>
<%- end -%>

As soon as this role is running on CentOS 8, the job will be stopped after foreman_subnet and without error, only an exit status 0

[...]
      subnet:
        boot_mode: Static
        description: ''
        dns_primary: x.x.x.x
        dns_secondary: x.x.x.x
        from: ''
        gateway: x.x.x.x
        ipam: None
        mask: 255.255.255.0
        mtu: 1500
        name: x.x.x.x
        network: x.x.x.x
        network_type: IPv4
        to: ''
        vlanid: null
      subnet6: null
      tag: null
      type: Interface
      virtual: false
    foreman_subne
Exit status: 0

Unfortunately, my ansible role will never run.
As anyone an Idea what could be the problem? Is it a known issue?

Thanks and best regards,
H.
