Deploy failed due to CustomLoadDataProducts

[jingnanl]

I'm trying to deploy the solution with the latest code (commit a45530a) but failed.

Status reason Embedded stack arn:aws:cloudformation:us-west-2:012870276471:stack/retaildemostore-DeploymentSupport-7F45MPQBWCLN/f7d34d10-66a2-11ef-b88d-069aa8cc439f was not successfully created: The following resource(s) failed to create: [CustomLoadDataProducts].

Look into the nested stack DeploymentSupport

CloudFormation did not receive a response from your Custom Resource. Please check your logs for requestId [86b3e845-2b18-4176-82dc-b911199661a7]. If you are using the Python cfn-response module, you may need to update your Lambda function code so that CloudFormation can attach the updated version.

Not sure if it's related to the recent change of #624.
