Im having trouble trying to change my current aws_route53_record that has a web app, Im trying to decouple it and use a s3 static site, I’m trying the following

resource "aws_route53_zone" "site_zone" {
  name = "${var.site_name}"
}
resource "aws_route53_record" "site_cname" {
  zone_id = "${aws_route53_zone.site_zone.zone_id}"
  name = "${var.site_name}"
  type = "NS"
  ttl = "30"
  records = [
    "${aws_route53_zone.site_zone.name_servers.0}",
    "${aws_route53_zone.site_zone.name_servers.1}",
    "${aws_route53_zone.site_zone.name_servers.2}",
    "${aws_route53_zone.site_zone.name_servers.3}"
  ]
}

And my current config is

resource "aws_route53_record" "www-prod" {
  zone_id = aws_route53_zone.primary_route.id
  name    = var.domain
  type    = "A"

  alias {
    name                   = var.ecs-frontend-alb-dns-name
    zone_id                = var.ecs-frontend-alb-dns-zone-id
    evaluate_target_health = true
  }
}

is there anything I missed?

Thanks for the help!
