Region: ap-northeast-3 does not work.

[ktasper]

Describe the Bug

When trying to use this module with the new ap-northeast-3 region it does not work.

Expected Behavior

I expect it to create the subnets.

Steps to Reproduce

Steps to reproduce the behavior:

provider "aws" {
  region  = var.region
  profile = var.profile
}

module "vpc" {
  source     = "git::https://github.com/cloudposse/terraform-aws-vpc.git?ref=tags/0.25.0"
  cidr_block = var.cidr_block
  attributes = ["vpc"]
}

module "subnets" {
  source                          = "git::https://github.com/cloudposse/terraform-aws-dynamic-subnets.git?ref=tags/0.39.0"
  vpc_id                          = module.vpc.vpc_id
  igw_id                          = module.vpc.igw_id
  cidr_block                      = module.vpc.vpc_cidr_block
  availability_zones              = var.az
  aws_route_create_timeout        = "5m"
  aws_route_delete_timeout        = "10m"
}

variable "cidr_block" {
  default = "10.0.0.0/24"
}

variable "region" {
  default = "ap-northeast-3"
}
variable "profile" {
    default = "default" 
}
variable "az" {
  default = ["ap-northeast-3a","ap-northeast-3b","ap-northeast-3c"]
}

Will result in the following error:
