Ansible run from Satellite: delegate_to doesn't work

Hello, I'm using Red Hat Satellite 6.12.4.

I need to run the Ansible playbook on a remote server except for one task that I need to run locally on a Satellite server. I tried delegate_to, but it doesn't work.

How can I do it?

My playbook:

---
- hosts: all
  gather_facts: True
  tasks:
    - name: get server fqdn
      set_fact:
        server_fqdn: "{{ ansible_fqdn }}"

    - name: satellite server fqdn
      set_fact:
        satellite_fqdn: "{{ ansible_fqdn }}"
      delegate_to: satellite.example.net

    - name: print fqdn
      debug:
        msg: "SERVER={{ server_fqdn }} SATELLITE={{ satellite_fqdn }}"

and the output:

TASK [print fqdn] **************************************************************
ok: [test.example.net] => {
  "msg": "SERVER=test.example.net SATELLITE=test.example.net"
}
