[Bug]: Private network not included on server data source

[inakimalerba]

What happened?

When trying to fetch information about an existing server, for example, by using the following query, the resulting objects do not contain information about the private networks.

data "hcloud_servers" "masters" {
  with_selector = "role=master"
}

I think the issue is on this check, which apparently does not work when we're fetching the server information:

Also, the data schema does not contain a network field.

What did you expect to happen?

Be able to get the value of the private IP of a VM.

Please provide a minimal working example

data "hcloud_servers" "masters" {
  with_selector = "role=master"
}

output "masters" {
  value = data.hcloud_server.masters
}

output is

   masters = {
       id            = "redacted"
       servers       = [
           {
