How can I uncordon a node in an automatic cluster?

Hey, I'm learning Kubernetes on GKE. 

I created an Autopilot cluster, then ran `kubectl get nodes`, then `kubectl cordon <one of the two nodes>` on it. Now when I run `kubectl get nodes` again I see:

NAME STATUS ROLES AGE VERSION
gk3-super-cube-pool-2-45f5208b-h8j8 Ready <none> 21m v1.28.7-gke.1026000
gk3-super-cube-pool-2-c46ec490-2wcn Ready,SchedulingDisabled <none> 3h33m v1.28.7-gke.1026000

I found in Google that to undo the cordon I need to run `kubectl uncordon <node>` but then I got this:

(gcp-tests-2024)$ kubectl uncordon gk3-super-cube-pool-2-c46ec490-2wcn
error: unable to uncordon node "gk3-super-cube-pool-2-c46ec490-2wcn": admission webhook "warden-validating.common-webhooks.networking.gke.io" denied the request: GKE Warden rejected the request because it violates one or more constraints.
Violations details: {"[denied by autogke-no-node-updates]":["Uncordon on nodes is not allowed in Autopilot."]}

What is the solution here? I can't delete the node either

(gcp-tests-2024)$ kubectl delete node gk3-super-cube-pool-2-c46ec490-2wcn
Error from server (GKE Warden constraints violations): admission webhook "warden-validating.common-webhooks.networking.gke.io" denied the request: GKE Warden rejected the request because it violates one or more constraints.

Appreciate your help!

You shouldn't need to do much about it. After you cordoned the node nothing new will be scheduled to this node. To remove it you can delete / reschedule all pods that are running on it; once gone it should be deleted by autopilot automatically.
