I want to iterate over items, check if fluxcd value exist in any of the items, and if fluxcd doesn't exists I want to execute task using when condition. So far I wrote this:

- name: Check flux status
  k8s_facts: 
    api_version: v1
    kind: Namespace
    kubeconfig: "{{ kubeconfig if kubeconfig_exists else omit }}"
  register: namespace_result

- name: Delete flux 
  k8s: 
    state: absent
    definition: "{{ lookup('template', 'flux-deletion.yaml') }}"
    kubeconfig: "{{ kubeconfig if kubeconfig_exists else omit }}"
    wait: True
  when: item.metadata.name != "fluxcd"
  with_items: "{{ namespace_result.resources }}"    
  ignore_errors: yes

Output (debug code provided by: Zeitounator):

- debug:
    msg: "{{ item.metadata.name }} meets the condition"
  with_items: "{{ namespace_result.resources }}"
  when: item.metadata.name != "fluxcd"

But when I run this, it seems to me like it will check first field in the list where value is default and it will automatically execute task. I don't have experience with ansible, any help would be appreciated. Thanks.
