Hello World Expanded Example > InvalidAnnotationException

[crisp oracle]

I'm trying to run the docs "Expanded Example" found here: https://docs.litestar.dev/latest/

When I run it I get:
litestar.exceptions.dto_exceptions.InvalidAnnotationException: DTO narrowed with '<class 'my_app.models.User'>', handler type is '<class 'my_app.models.PartialUserDTO'>'

My file structure is as follows:

├── app.py
├── my_app
│   ├── controllers
│   │   └── user.py
│   ├── models.py

Is there something about the directory/file structure that is causing this? I was unclear where to copy past the code in the example.

Hello, you should have async def partial_update_user(self, user_id: UUID4, data: PartialUserDTO) -> User: can you check if changing that to
async def partial_update_user(self, user_id: UUID4, data: DTOData[User]) -> User: does anything?

As shown here https://docs.litestar.dev/latest/tutorials/dto-tutorial/09-updating.html#patch-handlers

Hey thanks, was my first time trying litestar, so had no idea what was wrong. I think your suggestion was correct, so I opened a PR to fix the doc I found the issue from:

Feel free to ask, there are a lot more users (better users than me) who can help you with all sorts of things 😇

also, mark this as solved then? so that other users don't end up revisiting this
