OS / ENVIRONMENT

MacOS/12.4 (21F79)/M1 (this is not OS specific issue)

STEPS TO REPRODUCE

- name: test
  hosts: host
  become: yes
  vars:
    ssh_port: 2222
    ansible_port: "{{ ssh_port }}"

  tasks:
    - name: sync
      ansible.posix.synchronize:
        # dest_port: "{{ ansible_port }}"
        mode: pull
        src: "user@host/file"
        dest: "~/"

EXPECTED RESULTS

All works. (if in PB uncomment line # dest_port: "{{ ansible_port }}" or comment line ansible_port: "{{ ssh_port }}" - all worked fine)

ACTUAL RESULTS

Jinja expression "{{ ssh_port }}" of variable ansible_port not substituted and sends to module as string (see below line dest_port: '{{ ssh_port }}'): https://github.com/ansible-collections/ansible.posix/blob/a65807edc322ec403eb73e006aa9f6e2172026a3/plugins/action/synchronize.py#L265-L268

[nikgalkin]

Have the same issue, my temporary workaround:

- name: test
  hosts: host
  vars:
    ssh_port: 2222
    ansible_port: "{{ ssh_port }}"

  tasks:
    - name: sync
      ansible.posix.synchronize:
        dest_port: "{{ lookup('ansible.builtin.vars', 'ansible_port') }}"
        mode: pull
        src: user@host/file
        dest: ~/
