crhelper appears tp break

[mrpackethead]

I've had issues when using crhelper to get it return attributes back to the stack.

This very simple lambda works.

def on_event(event, context):
	props = event["ResourceProperties"]
	print("create new resource with props %s" % props)
	message = event['ResourceProperties']['RERUN']

	product_id = sc.search_products_as_admin(
		Filters={
			'FullTextSearch': ['AWS Control Tower Account Factory']
		},
	)['ProductViewDetails'][0]['ProductViewSummary']['ProductId']
	
	artifact_id = sc.describe_product_as_admin(
		Id = product_id
	)['ProvisioningArtifactSummaries'][0]['Id']
	

	attributes = {
		'ProductId': product_id,	
		'ArtifactId': artifact_id
	}
	return { 'Data': attributes }

if i replace it with this;

import crhelper
import boto3

helper = crhelper.CfnResource()

@helper.create
@helper.update
def get_account_factory_id(event, _):

	sc = boto3.client('servicecatalog')

	
	product_id = sc.search_products_as_admin(
		Filters={
			'FullTextSearch': ['AWS Control Tower Account Factory']
		},
	)['ProductViewDetails'][0]['ProductViewSummary']['ProductId']
	helper.Data['ProductId'] = product_id
	
	artifact_id = sc.describe_product_as_admin(
		Id = product_id
	)['ProvisioningArtifactSummaries'][0]['Id']
	helper.Data['ArtifactId'] = artifact_id
	
	
@helper.delete
def no_op(_, __):
	pass

def on_event( event, context ):
	helper(event, context)

I end up with this error.

The stack named AccountfactoryStack failed to deploy: CREATE_FAILED (CustomResource attribute error: Vendor response doesn't contain ArtifactId key in object arn:aws:cloudformation:ap-southeast-2:4xxxxxxxx7:stack/AccountfactoryStack/71875c50-f5a8-11ec-ac83-06c5a6d5f3f0|accountTahiprovisioningArtifactIdD6FC5169|5c9f7268-d6e5-45f5-b2fb-8cafdb68e1ee in S3 bucket cloudformation-custom-resource-storage-apsoutheast2)

It appears that somethign might be broken here. I love the idea of crhelper, its great, but not being able to use attributes is a killer.
