Eks assume policy error when using templatefile

Terraform
1

Hello, I want write assume policy that handles both clutser within same aws account.
I tried to use templatefile for assume_policy and then pass the ocid of two clusters as a list.

I tried the following but getting an error. Using terraform 0.12.28

locals.tf

  federated = [
    "xxxxxxxxxxxxxxxxxxxx",
    "yyyyyyyyyyyyyyyyyyyyy"
  ]

     federatedList1 = [for oidc in local.federated : "arn:aws:iam::2222222222:oidc-provider/oidc.eks.us-east-1.amazonaws.com/id/${oidc}"]
      federatedList2 = join("", [for oidc in local.federated : "\"oidc.eks.us-east-1.amazonaws.com/id/${oidc}:sub:\", \"system:serviceaccount:%s:%s\""])

eks_assume_policy.json.tpl

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Federated": ["${federatedList1}",]
      },
      "Action": "sts:AssumeRoleWithWebIdentity",
      "Condition": {
        "StringEquals": {
          "${federatedList2}"
        }
      }
    }
  ]
}

My goal is to use this policy in role .

resource "aws_iam_role" "launcher" {
  name               = local.Launcher
  assume_role_policy =format(templatefile("./eks_assume_policy.json.tpl", {
    federatedList1 = "${local.federatedList1}"
    federatedList2 = "${local.federatedList2}" }), "my-namepsace", local.Launcher)

  tags = {
    terraform = "true"
    owner     = "stg"
  }
}

Error:

Error: Error in function call

on role.tf line 49, in resource “aws_iam_role” “launcher”:
49: assume_role_policy = format(templatefile(“./eks_assume_policy.json.tpl”, {
