Creating a firewall rule with target “This Firewall” fails

[ZzenlD]

Hello,
I would like to allow DNS requests to the firewall for each subnet. In the Web UI, I can select “This Firewall” as the destination and everything works.

I have now created the following Ansible task for this

- name: Allow DNS requests to the firewall
  ansibleguy.opnsense.rule:
    interface: LAN
    action: pass
    protocol: TCP
    destination_net: This Firewall
    destination_port: 53
    description: Allow DNS-Queries
    match_fields: ["description"]
    firewall: <host>
    api_key: <key>
    api_secret: <secret>

But now I get the error message This Firewall is not a valid source IP address or alias..

Does anyone have a solution for this or what am I doing wrong?
