I just had a similar issue which I managed to resolve with aws support. The issue I was having was that the cluster was created with a role that was assumed by the user, but kubectl was not assuming this role with the default kube config created by the aws-cli.

I fixed the issue by providing the role in the users section of the kube config

users:
- name: aws
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1alpha1
      args:
      - token
      - -i
      - test
      - -r
      - <arn::of::your::role>
      command: aws-iam-authenticator
      env:
      - name: AWS_PROFILE
        value: personal

I believe the heptio-aws-authenticator has now been changed to the aws-iam-authenticator, but this change was what allowed me to use the cluster.
