CloudFormation did not receive a response from your Custom Resource. Please check your logs for requestId [2cceedaf-dbdb-4ed9-95ba-10cb948ce3ea]. 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.

After fixing some issues with the incorrectly named Lambda zip you need to upload (should be "cfnResponse_layer.zip") and an empty result for `${AWS::Partition}` for me in the Frankfurt region (if you are not in a government cloud, just hardcode "aws"), I am running into this issue:

```

I am not sure what I can do here... the `domain_function` Lambda layer simply imports `cfnresponse`, nowhere is there a package version specified. Also, all the Lambdas are already configured for Python 3.8, which doesn't seem too old as per time of writing.

I googled around and found [this page](https://aws.amazon.com/premiumsupport/knowledge-center/cloudformation-cfn-response-lambda/). Does this mean that there is a Lambda somewhere in my account that already defines a cfn-response but is outdated?
