loopback_ipv4_address under node: not resolve the variable input

[jixh99]

Issue Summary

The dict key "loopback_ipv4_address" not resolve the inputs as variable, while other keys do, like "mgmt_ip" and "bgp_as".

the AVD inputs:

l3leaf:
defaults:
platform: cEOS
loopback_ipv4_pool: "{{ NETv4_LPBK_ULAY }}"
loopback_ipv4_offset: 0
...
nodes:
- name: cleaf01
id: 1
loopback_ipv4_address: "{{ NETv4_LPBK_ULAY | ansible.utils.ipaddr(2) | ansible.utils.ipaddr(address) }}"
mgmt_ip: "{{NETv4_MGMTA | ansible.utils.ipaddr(seq_id) }}"
bgp_as: "{{ bgp_asn_base + dc_id*100 + seq_id }}"

How do you run AVD ?

Ansible CLI (with virtual-env or native python)

Steps to reproduce

# L3 Leaf switch group
l3leaf:
  defaults:
    platform: cEOS
    loopback_ipv4_pool: "{{ NETv4_LPBK_ULAY }}"
    loopback_ipv4_offset: 0
    vtep_loopback_ipv4_pool: "{{ NETv4_LPBK_OLAY }}"
    uplink_switches: ['spine01', 'spine02']
    uplink_ipv4_pool: "{{ NETv4_PTP }}"
    virtual_router_mac_address: 00:1c:73:{{'%02d' % rack_id}}:{{'%02d' % rack_id}}:99
    spanning_tree_priority: 4096
    spanning_tree_mode: mstp

  nodes:
    - name: cleaf01
      id: 1
      loopback_ipv4_address: "{{ NETv4_LPBK_ULAY | ansible.utils.ipaddr(2) | ansible.utils.ipaddr(address) }}"
      mgmt_ip: "{{NETv4_MGMTA | ansible.utils.ipaddr(seq_id) }}"
      bgp_as: "{{ bgp_asn_base + dc_id*100 + seq_id }}"
      uplink_switch_interfaces:
        - Ethernet1
        - Ethernet1

Relevant log output

My guess is that address needs to be enclosed in single quotes to be picked up as a string instead of an undefined variable.
Unfortunately Ansible stops templating of vars (silently) if any errors are hit.
