Example Codefrom typing import Annotated
from fastapi import FastAPI, Form
app = FastAPI()
@app.post('/login')
def login(
username: str = Annotated[str, Form()],
password: str = Annotated[str, Form()],
):
return {'username': username}DescriptionFirst of all, when I open Swagger, instead of body parameters 
It "works", but that's not the result I expect. When I make request properly using Insomnia or Bruno: curl --request POST \
--url http://127.0.0.1:8000/login \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'User-Agent: insomnia/2023.5.8' \
--data username=a \
--data password=bI get 500 Internal Server Error with the following traceback: Operating SystemmacOS Operating System DetailsNo response FastAPI Version0.111.0 Pydantic Version2.7.1 Python VersionPython 3.9.19 Additional ContextAn example above is the same as in https://fastapi.tiangolo.com/tutorial/request-forms/ |

You're not using correctly Annonated, change to this: from typing import Annotated
from fastapi import FastAPI, Form
app = FastAPI()
@app.post('/login')
def login(
username: Annotated[str, Form()],
password: Annotated[str, Form()],
):
return {'username': username} |

Oh my, I was literally staring at my code and docs for 5 minutes, not seeing any difference. |
