KeyError: 'Standard_F4s_v2'

Hi,

I have created multiple agentpools with different vm_size and got errors after autoscaler installed. The flag of ignorepools has no effect, error still exists.

The error logs can be follows:

KeyError: 'Standard_F4s_v2'

When there is only one vm_size in agentpools, the autoscaler was back to normal.

Other useful informations:

My vm_size:

  memory_pool = {
    name            = "memory"
    count           = 4
    vnet_subnet_id  = "${local.vnet_subnet_id}"
    vm_size         = "Standard_DS2_v2"
    os_disk_size_gb = 512
    storage_profile = "ManagedDisks"
  }

  memory_plus_pool = {
    name            = "memoryplus"
    count           = 1
    vnet_subnet_id  = "${local.vnet_subnet_id}"
    vm_size         = "Standard_D8s_v3"
    os_disk_size_gb = 512
    storage_profile = "ManagedDisks"
  }

  compute_pool = {
    name            = "compute"
    count           = 1
    vnet_subnet_id  = "${local.vnet_subnet_id}"
    vm_size         = "Standard_F4s_v2"
    os_disk_size_gb = 512
    storage_profile = "ManagedDisks"
  }

  storage_pool = {
    name              = "storage"
    count             = 1
    vnet_subnet_id    = "${local.vnet_subnet_id}"
    vm_size           = "Standard_L4s"
    os_disk_size_gb   = 512
    storage_profile   = "ManagedDisks"
    data_disk_size_gb = "[1023]"
