Unknown error with arguments of roles

Hi all,

I have a role lr_nsupdate so:
- - -
- name: Show calling args
  debug:
    var: ca

- name: Update DNS master server
  community.general.nsupdate:
    key_name: '{{ key_name }}'
    key_algorithm: '{{ algorithm }}'
    key_secret: '{{ secret }}'
    server: '{{ server }}'
    zone: '{{ ca.zone | default(None) }}'
    record: '{{ ca.owner_name }}'
    ttl: '{{ the_ttl | default(3600) }}'
    type: '{{ ca.type }}'
    value: '{{ ca.RDATA }}'
    state: '{{ ca.state | default(present) }}‘
- - -
When I call it so in another role:
- - -
- name: 'Delete CNAME db.lrau.net'
  include_role:
    name: lr_nsupdate
  vars:
    ca:
      ca.owner_name: 'db.lrau.net.'
      ca.state: 'absent'
      ca.type: ‚CNAME‘
- - -
I get:
- - -
ok: [dbo5] => {
    "ca": {
        "ca.owner_name": "db.lrau.net.",
        "ca.state": "absent",
        "ca.type": "CNAME"
    }
}

TASK [lr_nsupdate : Update DNS master server] **************************************************************************************************************************************************************************************************************
fatal: [dbo5]: FAILED! => {"msg": "The task includes an option with an undefined variable.

Any help welcome,

You either change it to ca.ca.owner_name or remove the second ‘ca’ for each dict member.

Naturally of course, (-;

After fixing the argument issue, I’m stuck with this:

I have a role lr_nsupdate so:
- - -

    record: '{{ ca.owner_name }}'
    ttl: '{{ the_ttl | default(3600) }}'
    type: '{{ ca.type }}'
    value: '{{ ca.RDATA | default(None) }}'
    state: "{{ ca.state | default('present') }}"

Is this a bug in the nsupdate module?

Thanks, Axel

Those default(None) should probably be default(omit).

Is this a bug in the nsupdate module?

I expect it is, or at least it could be handled better. But my guess is it’s being triggered by your use of None instead of omit.
