VMWARE_EX host mode invalid

[a-dawg]

hey,
It looks like there is a bug when trying to use the VMWARE_EX host mode

hitachi_vsp_hostgroup.hg["xxx"]: Refreshing state... [id=CL2-A4]
╷
│ Error: invalid hostmode specified VMWARE_EX
│ 
│   with hitachi_vsp_hostgroup.hg["xxxx"],
│   on main.tf line 47, in resource "hitachi_vsp_hostgroup" "hg":
│   47: resource "hitachi_vsp_hostgroup" "hg" {

when using

resource "hitachi_vsp_hostgroup" "myhg" {
  serial           = 12345 
  hostgroup_number = 23
  hostgroup_name   = "TESTING-HOSTGROUP" 
  port_id          = "CL1-A"           
  host_mode_options = [12, 32]
  host_mode         = "VMWARE_EX"

  # SET of LUN
  lun {
    ldev_id = 25
    lun     = 12
  }
}
