Cannot login in fastapi-webapp-with-auth

[RuiNov1st]

Hello, I've tried your code on 2022-04-14-fastapi-webapp-with-auth.
But when I enter username and password and submit, it still redirect to home and show "You are NOT logged in". But in terminal, log says "Login successful!!!!".
And when I try to access /private, it show "AttributeError: 'str' object has no attribute 'removeprefix'".
Is there any mistake in my operation and how can I fix it? Thanks!

Well. It seems that I can handle it. In function decode_token, token = token.removeprefix("Bearer").strip() could be replaced by for example:

if token.startswith('Bearer'):
        token = token[len('Bearer'):].strip()

because the methodstr.removeprefix() support only python 3.9+. And I use python 3.8.
And after I modified it, it could login successfully.
Sorry for the native question.

No bad questions! Thank you for starting the issue and sharing your fix. I should document the minimum python version to help future users!
