Allow_overwrite route 53 record causes an error

Terraform Providers AWS
1

With this config, Idea is to overwrite the existing route 53 record if the environment needs a DR . But I am getting this error -

RRSet with DNS name <dns_name>., type A, SetIdentifier dev-dr-primary, and marked as primary cannot be created because a non-failover RRSet with the same name and type already exists.

by default the first route53 record will be created and I am trying to overwrite the record conditionally

resource "aws_route53_record" "domain" {
  zone_id = var.route_53_zone
  name    = var.api_sub_domain
  type    = "A"

  alias {
    name                   = module.nlb.lb_dns_name
    zone_id                = module.nlb.lb_zone_id
    evaluate_target_health = false
  }
}
