Error producing mock for object with inheritance

[rmgrimm]

The attached specification demonstrates the issue: ExampleProblem.json.txt (adding .txt file extension so GitHub will allow me to upload)

Running with:

openapi-mock -u ExampleProblem.json serve

and then hitting http://localhost:8080/example will cause the error.

The relevant part of the log seems to be:
