Failed to update node registry: Unable to get first autoscaling.Group for [node-group-name]

Hello, I am new to EKS, I am following this link to create worker nodes where i am using combination of on demand as well as spot instances.

https://aws.amazon.com/blogs/compute/run-your-kubernetes-workloads-on-amazon-ec2-spot-instances-with-amazon-eks/

[ec2-user@ip-192-168-100-253 ec2-spot-eks-solution]$ kubectl get nodes

While using cluster auto-scaler, i am getting below errors.

Here is cluster-autoscaler policy which is attached to NodeInstanceRole

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [

                "autoscaling:SetDesiredCapacity",
                "autoscaling:DescribeTags",
                "autoscaling:TerminateInstanceInAutoScalingGroup",

            "Effect": "Allow",
            "Sid": "K8NodeASGPerms"
        }
    ]
}

cluster-autoscaler-ds.yaml
command:
            - ./cluster-autoscaler
            - --v=4
            - --stderrthreshold=info
            - --cloud-provider=aws
            - --skip-nodes-with-local-storage=false
            - --expander=least-waste
            - --nodes=1:3:[<REDACTED>]
            - --nodes=1:3:[<REDACTED>]
            - --nodes=1:3:[<REDACTED>]
            - --skip-nodes-with-system-pods=false
          env:
            - name: AWS_REGION
              value: eu-central-1

Am i missing something?

@mperi Any clues?

Figured out the issue myself.. I had extra un-necessary [ ] in --nodes=1:3:[<REDACTED>]
