Cannot communicate with my Kubernetes Cluster using Terraform

I was trying to get started with AWS EKS Kubernetes cluster provisioning using Terraform. I was following the tutorial and got stuck on the moment with the kubeconfig file. After the command: terraform output kubeconfig > ~/.kube/config, I should be able to communicate with the cluster. Unfortunately, when I try to use any command together with kubectl, for example cluster-info, I get an error error loading config file, yaml: line 4: mapping values are not allowed in this context

This is the code of the outputs.tf file:

# Outputs

locals {
  config_map_aws_auth = <<CONFIGMAPAWSAUTH


apiVersion: v1
kind: ConfigMap
metadata:
  name: aws-auth
  namespace: kube-system
data:
  mapRoles: |
    - rolearn: ${aws_iam_role.demo-node.arn}
      username: system:node:{{EC2PrivateDNSName}}
      groups:
        - system:bootstrappers
        - system:nodes
CONFIGMAPAWSAUTH

  kubeconfig = <<KUBECONFIG


apiVersion: v1

    server: ${aws_eks_cluster.demo.endpoint}

      args:
        - "token"
        - "-i"
        - "${var.cluster-name}"
KUBECONFIG
}

output "config_map_aws_auth" {
  value = local.config_map_aws_auth
}

output "kubeconfig" {
  value = local.kubeconfig
}```
