Hi,
Got the app working but when I to generate the AWS diagram it says " Unfortunately, I do not have access to any Python libraries or tools in this environment that can generate architecture diagrams from code."

Also when trying to generate cdk script it says "The output shows that the aws-cdk library is not installed in this environment, so I cannot create a Python CDK script"

Please advise,

Thanks
