cfn generate not creating models.

Typescript resource models are not being generated by cfn generate. A similar workflow using java generates the S3 and BucketPolicy models, but nothing with typescript.

Environment Details:
Windows 10 Pro
cfn 0.2.28
Python 3.10.10
Node v18.13.0

Same results with:
Mac OS 12.6.3
cfn 0.2.28
Python 3.9.16
Node v18.12.1
