for_each in dns_a_record_set might be a dependency issue

[lazyfrosch]

If you play around with depends_on this can cause issues.

│   on .terraform/modules/something/network.tf line 18, in data "dns_a_record_set" "subnet_dns":
│   18:   for_each = toset(data.qip_v4subnet.net.dns_servers)
│     ├────────────────
│     │ data.qip_v4subnet.net.dns_servers is a list of string, known only after apply
│ 
│ The "for_each" set includes values derived from resource attributes that cannot be determined until apply, and so Terraform cannot determine the full set of keys that will identify the instances of this resource.
