Hi @ascheffeapi, thanks for your interested in this package. The typescript version is updated to ^4.2.0 for the issue related with "Type 'IsTuple' is not generic". Can you test if this works for you?

Regarding the error related with "Cannot find module '@aws-cdk/aws-route53'", did you change the code to suit your use case? If this is the case, can you check if you have aws-route53 etc added in the dependencies in the package.json?
