FastAPI GET request exposes parameters from Depends()

I was using python 3.8 and an old version of FastAPI (0.75.0) and when I did this

from fastapi import Depends, FastAPI 
from fastapi.security import OAuth2PasswordBearer 
from typing_extensions import Annotated 

app = FastAPI() oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token") @app.get("/items/") 

async def read_items(
	token: Annotated[str, Depends(oauth2_scheme)]
): 
	return {"token": token}

On swagger, the route said it had parameters, and any requests made without a body would fail with something like missing detail.

The issue was the Annotated. As soon as I removed this, the route didn’t expose the parameters from Depends():

@router.get("/me")
async def read_items(token: str = Depends(oauth2_scheme)):
	return {"token": token}

Maybe support for Annotated was added in a later version of FastAPI
