[BUG]: ap-southeast-4 region missing from region module locals

[tac-ap]

Is there an existing issue for this?

• I have searched the existing issues

Description of the bug

When attempting to assign a kms key as the default ebs encryption key in the ap-southeast-4 region, I get the following error:

Error: Invalid index

on outputs.tf line 8, in output "code":
8: value = local.region_codes[data.aws_region.this.id]
├────────────────
│ data.aws_region.this.id is "ap-southeast-4"
│ local.region_codes is object with 25 attributes

it appears to be due to the referenced locals not including the region provided:
locals {
region = data.aws_region.this.name
region_codes = {
"us-east-1" = "use1"
"us-east-2" = "use2"
"us-west-1" = "usw1"
"us-west-2" = "usw2"
"af-south-1" = "afs1"
"ap-east-1" = "ape1"
"ap-northeast-1" = "apne1"
"ap-northeast-2" = "apne2"
"ap-northeast-3" = "apne3"
"ap-southeast-1" = "apse1"
"ap-southeast-2" = "apse2"
"ap-southeast-3" = "apse3"
"ap-south-1" = "aps1"
"ca-central-1" = "cac1"
"eu-central-1" = "euc1"
"eu-west-1" = "euw1"
"eu-west-2" = "euw2"
"eu-west-3" = "euw3"
"eu-north-1" = "eun1"
"eu-south-1" = "eus1"
"me-south-1" = "mes1"
"sa-east-1" = "sae1"
"cn-north-1" = "cn1"
"us-gov-west-1" = "usgw1"
"us-gov-east-1" = "usge1"
}
}

the output "code" then fails due to the current region not being included in the locals.

output "code" {
description = "The short code of the current region."
value = local.region_codes[data.aws_region.this.id]
}

Steps To Reproduce

Using terragrunt:

terraform {
source = "tfr:///tedilabs/account/aws//modules/region?version=0.30.4"
}

inputs = {
ebs_default_encryption = {
enabled = true
kms_key = ""
}
}

terragrunt run-all plan --terragrunt-non-interactive

data.aws_region.this: Reading...
data.aws_region.this: Read complete after 0s [id=ap-southeast-4]

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:

• create

Terraform planned the following actions, but then encountered a problem:

aws_ebs_default_kms_key.this[0] will be created

• resource "aws_ebs_default_kms_key" "this" {
  • id = (known after apply)
  • key_arn = "arn:aws:kms:ap-southeast-4:000000000000:key/aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"

• resource "aws_ebs_encryption_by_default" "this" {
  • enabled = true
  • id = (known after apply)

    • "module.terraform.io/version" = "0.30.4"
      }
  • type = "LOCAL"
    }
