How do I resolve an unauthorized server error when I connect to the Amazon EKS API server?

mapUsers: |
 - userarn: arn:aws:iam::XXXXXXXXXXXX:user/testuser
   username: testuser
   groups:
     - system:masters

mapRoles:

aws eks update-kubeconfig --name eks-cluster-name --region aws-region --role-arn
