Breaking Changes - Fixes

• 🐛 Fix response_model not invalidating None. PR #2725 by @​hukkin.

If you are using response_model with some type that doesn't include None but the function is returning None, it will now raise an internal server error, because you are returning invalid data that violates the contract in response_model. Before this release it would allow breaking that contract returning None.

For example, if you have an app like this:

from fastapi import FastAPI
from pydantic import BaseModel
class Item(BaseModel):
name: str
price: Optional[float] = None
owner_ids: Optional[List[int]] = None
app = FastAPI()
@​app.get("/items/invalidnone", response_model=Item)
def get_invalid_none():
return None

...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:

from fastapi import FastAPI
from pydantic import BaseModel
class Item(BaseModel):
name: str
price: Optional[float] = None
owner_ids: Optional[List[int]] = None
app = FastAPI()
@​app.get("/items/invalidnone", response_model=Item)
def get_invalid_none():
if flag:
return {"name": "foo"}
# if flag is False, at this point the function will implicitly return None

If you have path operations using response_model that need to be allowed to return None, make it explicit in response_model using Union[Something, None]:
