Provider Crashs when NIC IPs is a list with an emtpy string

Description

When i create a vm with a NIC, the provider will crash when the user only supply an list with an empty string.

The resource will be created when:

  • local.vm_ip is a ip_address
  • null

But the provider will crash if the user provides only an emtpy string for example aka

locals {
  vm_ip = ""
}

Expected behavior

When IPs is a List with an empty the string, the VM should be created without a specified ip or the provider should throw an error in the terraform plan phase.

Environment

Terraform version:

1.3.9

Provider version:

v6.3.5

OS:

MacOS Ventura 13.2.1

Configuration Files

How to Reproduce

locals {
  vm_ip = ""
}

resource "ionoscloud_server" "virtual_machine" {
  name              = var.name
  datacenter_id     = var.datacenter_id
  cores             = var.cpu_cores
  ram               = var.memory
  availability_zone = "AUTO"
  cpu_family        = var.cpu_family
  image_name        = data.ionoscloud_image.image.id
  image_password    = random_password.server_image_password.result
  type              = "ENTERPRISE"
  volume {
    name              = "${var.name}_volume"
    size              = 15
    disk_type         = "SSD Standard"
    user_data         = data.cloudinit_config.virtual_machine.rendered
    bus               = "VIRTIO"
    availability_zone = "AUTO"
  }
  nic {
    lan             = var.network_id
    name            = "${var.name}_nic"
    dhcp            = true
    firewall_active = false
    ips             = [local.vm_ip]
  }

  label {
    key   = "labelkey1"
    value = "labelvalue1"
  }
  label {
    key   = "labelkey2"
    value = "labelvalue2"
  }

  lifecycle {
    ignore_changes = [volume[0].user_data]
  }
}
