How to ensure that POD is deleted using ansible?

I am trying to validate that the pod is deleted. 

- name: Verify whether the POD is deleted
  command: "{{ local_kubectl }} get pod {{ pod_name}}"

but the task is failing as the command displays error as below

'Error from server (NotFound): pods ....'

But this is expected when i am checking for deletion of pod.

How to pass this task when it returns an error message?

Late response. Hope it is helpful to someone. https://docs.ansible.com/ansible/latest/collections/kubernetes/core/k8s_module.html

- name: Delete pod
  kubernetes.core.k8s:
    state: absent
    kind: Pod
    name: "{{pod_name}}"
    namespace: "{{test_ns}}"
    kubeconfig: "{{ config }}"
    wait: true
    wait_condition:
      status: False #wait for status to be false
    wait_sleep: 2  #check every 2 secs

Try k8s_facts

- k8s_facts:
    kind: Pod
    name: "{{ pod_name}}"
  register: result
- debug:
    var: result

(not tested)

You can just directly specify this using the k8s module

- name: Delete the POD
  k8s:
    api_version: v1
    kind: Pod
    namespace: "{{ k8s_namespace }}"
    name: "{{ pod_name }}"
    state: absent

Another path is to redefine "failure" to check for the expected result string.

- name: Verify whether the POD is deleted
  command: "{{ local_kubectl }} get pod {{ pod_name}}"
  register: verify
  failed_when: "'NotFound' not in verify.stderr"
