ValueError: Fn::GetAtt not allowed to be nested in Fn::Cidr.
Using cf2tf v0.6.2 and the CF file "fullstack-master.yaml" available here: https://github.com/aws-samples/aws-bookstore-demo-app/tree/main/template
When I built this tool, I put these rules in place based on AWS documentation. You can see at the bottom of this page https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference-cidr.html That the only functions allowed to be nested inside of Fn::Cidr are Ref and Select. What I have found is that the documentation is pretty much useless.
Thanks for reporting, will have this fixed soon.
