Unable to create node object manually in EKS - kubernetes

Question

I'm trying to setup kubedge with cloudcore in EKS (k8s version 1.21.12) and edgecore in an external server. As part of the kubeedge setup, I had to create a node object manually in cloudside which will be labelled as edge node.
But when I do the kubectl apply -f node.json, I'm getting the following response:
C:\Users\akhi1\manifest>kubectl apply -f node.json
node/edge-node-01 created
C:\Users\akhi1\manifest>kubectl get nodes
NAME STATUS ROLES AGE VERSION
ip-xx-xx-xxx-213.ap-southeast-1.compute.internal Ready <none> 3h48m v1.21.12-eks-xxxx << this node was already in my eks cluster
As you can see, I'm not able see the newly created node 'edge-node-01' in the list.
On checking the kube events, I got the following:
C:\Users\akhi1\manifests>kubectl get events
LAST SEEN TYPE REASON OBJECT MESSAGE
13m Normal DeletingNode node/edge-node-01 Deleting node edge-node-01 because it does not exist in the cloud provider
For manually node registration, I followed this doc:
https://kubernetes.io/docs/concepts/architecture/nodes/#manual-node-administration
My node.json would look like this:
{
"kind": "Node",
"apiVersion": "v1",
"metadata": {
"name": "edge-node-01",
"labels": {
"name": "my-first-k8s-edge-node"
}
}
}
I have also checked, node restriction and admission controller but couldn't find anything related to it.
Please let me know why, eks is blocking me to create a node object that doesn't have an underlying ec2 attached.
Thanks in advance,
Akhil
