  There was a table set out under a tree in front of the house,
and the March Hare and the Hatter were having tea at it:  a
Dormouse was sitting between them, fast asleep, and the other two
were using it as a cushion, resting their elbows on it, and talking
over its head.  `Very uncomfortable for the Dormouse,' thought Alice;
`only, as it's asleep, I suppose it doesn't mind.'

  The table was a large one, but the three were all crowded

...calling the path `/items/invalidnone` will raise an error, because `None` is not a valid type for the `response_model` declared with `Item`.

You could also be implicitly returning `None` without realizing, for example:

```Python
from fastapi import FastAPI
from pydantic import BaseModel

class Item(BaseModel):
    name: str
    price: Optional[float] = None
