panos_interface cannot configure layer2 interface

[laurent-perrin]

I'm trying to set an interface as layer2 to configure subinterfaces:

- name: configure interfaces
  panos_interface:
    ip_address: "{{ inventory_hostname }}"
    api_key: "{{ ansible_api_key }}"
    enable_dhcp: false
    if_name: "{{ item.name }}"
    mode: "{{ item.mode }}"
    zone_name: "{{ item.zone }}"
    ip: "{{ item.ip_address | default(omit) }}"
    management_profile: "{{ item.management_profile | default(omit) }}"
    commit: false
    state: present
  loop: "{{ interfaces }}"
  when: interfaces is defined
  notify: commit
  run_once: true
  tags: interfaces

But I got this error:

he full traceback is:

}

This same code is working for layer3 interfaces.
