It fails with a generic error (500) on the deployment end and with `:ERROR:localstack.services.cloudformation.cloudformation_starter: Unable to parse and create resource "HelloEventSourceMappingDynamodbFooTable": 'NoneType' object has no attribute 'function_arn'` on the localstack end.
It deploys fine to AWS.
