AWS could not get token: AccessDenied: User: ARN is not authorized to perform: sts:AssumeRole on resource: Role:ARN

I am following the step guide to set up and kubernetes environment on AWS.

https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html#role-create

It already had some gochchas.. and they have been answered partially.

1. https://stackoverflow.com/questions/51135795/error-the-server-doesnt-have-resource-type-svc
2. https://stackoverflow.com/questions/50791303/kubectl-error-you-must-be-logged-in-to-the-server-unauthorized-when-accessing

For some reason, people were able to resolve using these guidelines available in these answers, and I still could not break it.

could not get token: AccessDenied: User: arn:aws:iam::sssssss:user/testprofileUser is not authorized to perform: sts:AssumeRole on resource: arn:aws:iam::sssssssss:role/eksServiceRole

What I have done:

1. I created an IAM user with Admin privileges.(servicesDev).
2. Created a IAM Role for EKS service (amazonEKSServiceRole)

amazonEKSServiceRole has a trust relationship as below,

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "eks.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

This is my kubeconfig file,

apiVersion: v1
clusters:
- cluster:
    server: https://7F30ANNSDSDMDCE1.ylq.us-east-1.eks.amazonaws.com
    certificate-authority-data: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0tLS0tCk1JSUN5RENDQWJDZ0F3SUJBZ0lCQURB...
  name: clouddev
contexts:
- context:
    cluster: clouddev
    user: aws
  name: aws
current-context: aws
kind: Config
preferences: {}
users:
- name: aws
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1alpha1
      command: aws-iam-authenticator
      args:
        - "token"
        - "-i"
        - "clouddev"
        - "-r"
        - "arn:aws:iam::xxxxx:role/amazonEKSServiceRole"
      env:
        - name: AWS_PROFILE
          value: "testprofile"

To be clear I have a testprofile setup correctly in ~/.aws/credentials

If anybody can shed some light greatly appreciated.
