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
  <!--- Please list the steps required to reproduce the issue. --->
  1. Ensure a Network on VLAN 0 exists on the target cluster and is not configured for Nutanix IPAM.
  2. `terraform apply`
