Is your feature request related to a problem? Please describe.
After upgrading to 0.19.0, I get this error when parsing my OpenAPI 3.0.3 yaml:

TypeError: conversion from UnionIntFloat to Decimal is not supported

I am guessing that it doesn't like some data format in my yaml. However, my yaml is over 9000 lines, and the error gives me no idea what object it was parsing when the error occurred, so I would have to go line by line to try and find it.

Describe the solution you'd like
When an exception is thrown during generation, show the path (such as components/schemas/MyObject/properties/myField) that was being parsed to aid in debugging

Describe alternatives you've considered
I've tried using the --debug flags and I tried taking a best guess at what the problem might be, but we're not having any success.
