Hey @zmievsa, could you please also port this to the 4.x.x release series?

We have to pin fastapi<=0.112.2 in our project because of the same issue.

@feluelle Hi! Which version of Cadwyn do you have? I remember fixing this problem in 4.x.x. However, I'm ready to fix it ASAP if it is a problem for you right now.

My tests indicate otherwise for now though.

Oh, we were on 4.2.2. Dependabot did not update our version for some reason, sorry 🤷🏼 It seems to have been fixed by updating to <4.4.0. I need to look into why 4.4.0 creates an openapi spec without any paths.

Any idea why that could be the case, @zmievsa? Happy to open a new issue for that.

Please, open a new issue. Any reproducible example would be fine. I'll be able to fix it within less than a day.

Hi, @feluelle !

Did the issue with paths resolve on its own or do you still need help? I have put aside time for it today so I can help as soon as you post the reproducible example. No rush though :)

I have been able to resolve the issue by calling app._cadwyn_initialize() before accessing the version router routes when generating the openapi spec.

That works for me, but do you have a recommended way of generating the openapi specs for each registered version? I couldn't find anything about that in the cadwyn docs.

Hmm, so it seems that this is a general issue in my fastapi app. The cadwyn __call__ function does not seem to get called which should call _cadwyn_initialize(). Any idea why that could be?

@feluelle Send me a minimal reproducible example, and I'll be able to help you solve the issue within the same day.

Here is a minimal example #229. PTAL when you find time.
