karpenter NodePool dry-run failed

[EigoOda]

I enabled conversion webhook when I upgraded Karpener to v1.
However, the Karpenter Pod was giving frequent TLS handshake errors and was noisy, so I disabled the Karpenter webhook.
The noisy logs disappeared, but the kustomization resource failed to dry-run the webhook and was no longer READY, so I re-enabled the webhook.
I re-enabled webhook, but now it continues to not READY with the following message.

NodePool/nodepool dry-run failed (Invalid): NodePool.karpenter.sh "nodepool" is invalid: [spec.disruption.consolidateAfter: Required value, <nil>: Invalid value: "null": some validation rules were no
t checked because the object was invalid; correct the existing errors to complete validation]

I had no problems until I upgraded to v1 and disabled webhooks.
And nodepool schema is correct and I can apply with kubectl apply without above error.

I tried to re-create the kustomization resource doesn't work.

Do you have any ideas?
Thanks.
