When I try to import an Amplify app into a CDK stack defined in python I get the following error after cdk synth. The same amplify app imported into a JavaScript CDK stack works.

$ node --version
v16.13.2

$ cdk --version
2.8.0 (build 8a5eb49)

    # python dependencies setup

The above exception was the direct cause of the following exception:
