#Codegen issue? (NameError: name 'UUID' is not defined)

I came back to my litestar code after a hiatus and upon startup I now get an error, which looks like might be in the codegen backend.
I'm using (as usual) latest litestar, but downgrading to 2.11 didn't help

Can you share your code as well?

Add UUID to your signature namespace

#

it was removed from the default signatures in Advanced Alchemy

Hi everyone - I think I am facing a similar problem after setting up a new environment with uv - I have NameError: name 'EmptyType' is not defined even though I never explicitly use it.

@teal zenith could you give me a hint where you added the import?

I added a full example here:
