Hi @taranjotkaur21,
Thanks for submitting the issue. I was on vacation for a few days.
I'll take a look today or tomorrow at the latest.

It looks like this is caused by a bug the underlying https://github.com/getkin/kin-openapi package.
It can be replicated by loading either one of the specs you provided here and noticing that some of the request bodies within the callbacks are not resolved.
@fenollp could you please take a look and let me know if you need more details to replicate.

Hi @reuvenharrison sorry I missed your hl.
Was this getkin/kin-openapi#757 the fix you were looking for?
Thanks

[reuvenharrison]

Yes @fenollp - this is the fix we needed.
Thanks!
