Wrong inferred type when using coercion?

[heivo]

Hi,

thanks for this awesome library!

I have a question, not sure if it's a bug in the library or if I'm doing it wrong:
I use coercion to automatically parse an ISO 8601 date string to a Date object. That works and the OpenAPI has the correctly type "string". However when I try to provide examples there is a TS type error:

I can fix it by providing Dates as examples, just wondering if that is how it's supposed to work.
