kubernetes - aws eks and aws sso RBAC authentication problem

Question

I have created a fresh AWS SSO (used internal IDP as identity source, so no use of Active Directory).
I am able to login to AWS CLI, AWS GUI, but unable to perform any kubectl ops.

error: You must be logged in to the server (Unauthorized)

This has something to do with the RBAC I think as I am able to get EKS token via aws eks get-token.

? cat ~/.aws/config

[profile team-sso-admin]
sso_start_url=https://team.awsapps.com/start
sso_region=us-west-2
sso_account_id=1111111111
sso_role_name=AdministratorAccess
region=us-west-2
credential_process = aws-vault exec team-sso-admin --json


? aws-vault exec team-sso-admin --debug -- zsh --login
