Mixing Request Forms and Files: pass additional parameters in a post request when file is transmitted

In the FAST API documentation, the below example is listed as a reference how to pass additional parameters in a post request when file is transmitted.

https://fastapi.tiangolo.com/tutorial/request-forms-and-files/

from fastapi import FastAPI, File, Form, UploadFile

app = FastAPI()


@app.post("/files/")
async def create_file(
    file: bytes = File(...), token: str = Form(...)
):

When I make a post request as below I get:

requests.post(URL, files={'file': hdf5_file, 'token': 'teststring'})

422 Unprocessable Entity
{'detail': [{'loc': ['body', 'model_str'],
   'msg': 'str type expected',
   'type': 'type_error.str'}]}

Why is token not recognized as a string? It's not clear from the documentation how a post request that mixes forms with files would need to look like.

For requests use the parameter files to upload files, and data for sending extra form data. In this case, everything will be sent as different parts with content-type multipart/form-data:

requests.post(URL, files={'file': hdf5_file}, data={'token': 'teststring'})
