terratest: Terraform Apply hang unresponsive

Terraform Project Structure:

-- terraform-root
---- main.tf
---- variables.tf
---- outputs.tf
---- test/
-------- basic_test.go
---- examples/
-------- elasticsearch-auth-iam-user/main.tf

my basic_test.go looks like the following

package test

import (
    "fmt"
    "testing"
    "github.com/gruntwork-io/terratest/modules/terraform"
)

func TestTerraformBasicExample(t *testing.T) {

	terraformOptions := &terraform.Options{
		TerraformDir: "../ examples/elasticsearch-auth-iam-user",

		Vars: map[string]interface{}{
                        "domain_name": "test",
            	        "stack": "elasticsearch",
                        "workspace": "stg",
		},
	}

	defer terraform.Destroy(t, terraformOptions)
	terraform.InitAndApply(t, terraformOptions)
}

cd into test run “go test -timeout 5m”.

I get “terraform init” succeeded but “terraform apply” hanged without any outputs until timing out.

Log looks like

If I comment module “elasticsearch_security_group” out. It works. Can it possible terratest has problem with module ?
