v2.12 breaks for IPv4 only setup

[kai-66degrees]

Description

I was using this module earlier and it was working perfectly however upgrading to v2.12 adds an error related to IPv6 configuration, which I am not using.

Rolling back to v2.11.1 solves the issue.

Error

Error: Missing required argument │ │ with module.aws-gcp-vpn-tunnels.module.vpn_gateway.aws_vpn_connection.tunnel_preshared[0], │ on .terraform/modules/aws-gcp-vpn-tunnels.vpn_gateway/main.tf line 304, in resource "aws_vpn_connection" "tunnel_preshared": │ 304: local_ipv6_network_cidr = var.local_ipv6_network_cidr │ │ "local_ipv6_network_cidr": all of │ local_ipv6_network_cidr,transit_gateway_id must be specified

Could someone provide a piece of configuration that breaks?

The following code works on version 2.11.1 but doesn't work on version 2.12.0

module "vpn_gateway" {
  source  = "terraform-aws-modules/vpn-gateway/aws"
  version = "2.12.0"

  vpc_id                                                              = module.vpc.vpc_id
  vpn_gateway_id                                              = module.vpc.vgw_id
  customer_gateway_id                                     = module.vpc.cgw_ids[0]
  vpn_connection_static_routes_only              = true
  vpn_connection_static_routes_destinations = [module.vpn_vpc.vpc_cidr_block]

  # precalculated length of module variable vpc_subnet_route_table_ids
  vpc_subnet_route_table_count = 3
  vpc_subnet_route_table_ids     = module.vpc.private_route_table_ids

  tags = {
    Name = var.name
  }
}
