Fastapi: Issue with docs Authorize button, gives 400 Bad Request in the security tutorial

[davidmckayv]

https://fastapi.tiangolo.com/tutorial/security/simple-oauth2/ or
https://fastapi.tiangolo.com/tutorial/security/oauth2-jwt/
When following either tutorial from above, a bad request is sent when clicking the localhost:8000/docs Authorize button using any username or password. Tried directly copying and pasting the code, the issue persists.

Environment

macOS
FastAPI 0.58.1
Python 3.7.7

Hello @davidmckayv - I'm just trying out FastAPI myself. Have you installed python-multipart?

pip install python-multipart

Then try with user johndoe and password secret.

Wow, I somehow missed the comment wherein it states this must be installed due to Ouath2 using "form data" for sending the username and password. All set.
