MissingEndpoint: 'Endpoint' configuration is required for this service

[lee5i3]

I'm having issues getting terratest to communicate to AWS, it creates the resources via terraform but terratest is says its missing the endpoint configuration

My terraform module creates RDS, my scenario returns the entire RDS object back so I can look into it

output "rds" {
  value = module.main
}

My test looks like the following

func Test_Defaults(t *testing.T) {
	t.Parallel()

	workingDir := "./scenarios/postgres"

	// At the end of the test, undeploy the web app using Terraform
	defer test_structure.RunTestStage(t, "cleanup_terraform", func() {
                // Temporarily commented out to keep resource around while testing verify code
		// Remove(t, workingDir)
	})

	// Deploy the web app using Terraform
	test_structure.RunTestStage(t, "deploy_terraform", func() {
		Deploy(t, workingDir, nil)
	})

	test_structure.RunTestStage(t, "validate", func() {
		ValidateAddressAndPort(t, workingDir, 5432)
	})
}

I am deploying my code with the following

func Deploy(t *testing.T, workingDir string, vars map[string]interface{}) {
	// Construct the terraform options with default retryable errors to handle the most common retryable errors in
	// terraform testing.
	terraformOptions := terraform.WithDefaultRetryableErrors(t, &terraform.Options{
		// The path to where our Terraform code is located
		TerraformDir: workingDir,

		// Variables to pass to our Terraform code using -var options
		Vars: vars,
	})

	// Save the Terraform Options struct, instance name, and instance text so future test stages can use it
	test_structure.SaveTerraformOptions(t, workingDir, terraformOptions)

	// This will run `terraform init` and `terraform apply` and fail the test if there are any errors
	terraform.InitAndApply(t, terraformOptions)
}

My validate looks like this

func ValidateAddressAndPort(t *testing.T, workingDir string, expectedPort int64) {
	options := test_structure.LoadTerraformOptions(t, workingDir)

	// Get Output
	output := terraform.OutputAll(t, options)

	// RDS output
	result := output["rds"].(map[string]interface{})

	// Variables
	region := fmt.Sprintf("%v", result["aws_region"])
	id := fmt.Sprintf("%v", result["id"])

	// Look up the endpoint address and port of the RDS instance
	address := aws.GetAddressOfRdsInstance(t, id, region)
	port := aws.GetPortOfRdsInstance(t, id, region)

	// Verify that the address is not null
	assert.NotNil(t, address)

	// Verify that the DB instance is listening on the port mentioned
	assert.Equal(t, expectedPort, port)
}

I'm getting an error while running says rds.go:18: MissingEndpoint: 'Endpoint' configuration is required for this service
I've tried using the aws.NewRDSClient but getting same error.. I'm not sure whats going on but maybe something to do with my AWS_PROFILE, I'm not using a default profile

I'm able to get to AWS via AWS CLI, and terraform can create the resources

I found the issue, region was not in my outputs.. so it was passing in null, was causing issues with the session
