How to provision infrastructure in a local zone using terraform? – Amazon Web Sevices

AWS recently introduced local zones (ap-south-1-del-1). I am trying to use the region to deploy an EC2 instance. I have enabled the region and the local zone in my AWS account.

This is my terraform provider file :-

provider "aws" {
  region = "ap-south-1-del-1"
}

terraform {
  required_version = "> 0.11"
  required_providers {
    aws = "~> 4.0"
  }
}

but i keep running into the following :-

 Error: error configuring Terraform AWS Provider: error validating provider credentials: 
 error calling sts:GetCallerIdentity: operation error STS: GetCallerIdentity, exceeded maximum 
 number of attempts, 9, https response error StatusCode: 0, RequestID: , request send failed, 
 Post "https://sts.ap-south-1-del-1.amazonaws.com/": dial tcp: lookup sts.ap-south-1-del- 
 1.amazonaws.com: no such host
│
│   with provider["registry.terraform.io/hashicorp/aws"],
│   on provider.tf line 1, in provider "aws":
│    1: provider "aws" {
│
╵

and this is my EC2 instance for anyone curious. Super basic.

resource "aws_instance" "web" {
  ami           = "ami-0ef82eeba2c7a0eeb"
  instance_type = "t2.micro"

  tags = {
    Name = "HelloWorld"
  }
}

Has anyone tried it? Is it supported? Thank you.
