Thanks for raising this @pjmagee

I suspect the error is thrown at https://github.com/std-uritemplate/std-uritemplate/blob/a85ad5c8a246f838769dc7792c8567b003eea330/python/stduritemplate/__init__.py#L316

Any chance you can share the openApi description or confirm if the request to the endpoint is taking a Date object as a url path parameter?

Indeed.

Thanks for confirming. This issue is related to microsoft/kiota-python#245. We also need to handled Date types similar to Guid values.

Would you be willing to submit a PR to fix this in the library?

My company makes it hard to work on this sort of thing.
