00040-verify failed when kube_node is empty

[lenglet-k]

What happened?

When i deploy from scratch a cluster i have this error:

TASK [kubernetes_sigs.kubespray.kubernetes/preinstall : Stop if either kube_control_plane or kube_node group is empty] **********************************************************************************************
ok: [control-plane-recette-1.x.z] => (item=kube_control_plane) => {
    "ansible_loop_var": "item",
    "changed": false,
    "item": "kube_control_plane",
    "msg": "All assertions passed"
}
failed: [control-plane-recette-1.x.z] (item=kube_node) => {
    "ansible_loop_var": "item",
    "assertion": "groups.get( item )",
    "changed": false,
    "evaluated_to": false,
    "item": "kube_node",
    "msg": "Assertion failed"
}

When i comment this code, it works:

 - name: Stop if either kube_control_plane or kube_node group is empty
   assert:
     that: "groups.get( item )"
   with_items:
     - kube_control_plane
     - kube_node
   run_once: true
   when: not ignore_assert_errors

What did you expect to happen?

it seems to be because my “kube_node” group is empty. Except that I start by installing my control-plane nodes first

How can we reproduce it (as minimally and precisely as possible)?

Deploy an environment with an inventory where kube_node group is empty
