I have a pydantic1 model class for error messages, but when I return Response(ErrorModel) from my exception handler I get type not supported
Am I doing something wrong?

Hey @brittle cobalt, sorry for the delay here!

#

I actually ran into this bug myself a couple of days ago. You're not doing anything wrong here, this seems to be a regression

#

We've had this bug before and it appears to have resurfaced now 🙂

I think it only appears if I forget to annotate the exception handler return type

#

it would mean there's not pre-flight check on that

#

hmm, wrote a minimal code and it still works... not sure why now

Description

When an handler raises an exception and exception handler returns a Response with a model (e.g. pydantic) object, encode that object with the app type_encoders.
