Resource "nutanix_subnet" fails when creating a managed IPAM network using a VLAN that overlaps with existing network

Nutanix Cluster Information

• Nutanix Cluster (Prism Element / AOS): 5.20.3
• Nutanix Prism Central: pc.2022.6.0.1

Terraform Version

Terraform v1.3.7
on windows_amd64

• provider registry.terraform.io/nutanix/nutanix v1.7.1

Affected Resource(s)

resource "nutanix_subnet"

Terraform Configuration Files

resource "nutanix_subnet" "next-iac-managed" {
  cluster_uuid = "<insertuuid>"

  name        = "next-iac-managed-example"
  vlan_id     = 0
  subnet_type = "VLAN"
  prefix_length = 20

  default_gateway_ip = "10.5.80.1"
  subnet_ip          = "10.5.80.0"

  dhcp_domain_name_server_list = ["8.8.8.8", "4.2.2.2"]
  dhcp_domain_search_list      = ["nutanix.com", "eng.nutanix.com"]
}

Expected Behavior

If there is not an existing VLAN 0 network with Nutanix IPAM enabled, the subnet should be created successfully (which the GUI allows). In addition, the error message is too ambiguous to understand the root cause.

Actual Behavior

Error: error waiting for subnet id (x) to create: error_detail: INTERNAL_ERROR: Subnet type provided is not supported, progress_message: create_subnet

The resource will only allow the subnet to be created when the VLAN is not 0. Changing the VLAN in the GUI post-create and updating the Terraform declaration functions as a workaround.

Steps to Reproduce

1. Ensure a Network on VLAN 0 exists on the target cluster and is not configured for Nutanix IPAM.
2. terraform apply
