target_id in below module is not accepting the organization id when set as a variable

[raghu-babloo]

module "custom-roles" {
  source = "terraform-google-modules/iam/google//modules/custom_role_iam"

  target_level         = "org"
  target_id            = "xxxxxxxxxxxxx"
  role_id              = "custom_role_id"
  title                = "Custom Role Unique Title"
  description          = "Custom Role Description"
  base_roles           = ["roles/iam.serviceAccountAdmin"]
  permissions          = ["iam.roles.list", "iam.roles.create", "iam.roles.delete"]
  excluded_permissions = ["iam.serviceAccounts.setIamPolicy"]
  members              = ["user:[email protected]", "group:[email protected]"]
}

Below is the error logs which is also not accurate as the issue is with target_id is not accepting the organization id when set as a variable.
