Google Oauth returning 404 on login

[ShaleenAg]

Describe the bug
I have added google oauth to my flower config, but whenever I try to login, it just errors out with Page not found and on checking the network tab, it seems like the login call is returning 404. I have tried using Basic auth and its working fine with it, so I am assumimg its a google issue.
Here's my config

auth_provider="flower.views.auth.GoogleAuth2LoginHandler"
auth=".*@domain.com"
oauth2_redirect_uri="https://dev.domain.com/flower/login/"
url_prefix='flower/'
#to make sure tasks stay populated after restarts
persistent=True
debug=True
oauth2_key="<redacted>.apps.googleusercontent.com"
oauth2_secret="<redacted>"

To Reproduce
Steps to reproduce the behavior:

1. Access flower from browser
2. login returns Error, page not found

Expected behavior
Flower should be logged in

Curious if you have found a way around this or a fix?

For future reference, it seems like the route is configured without the trailing slash, so the trailing slash leads to a 404. I think you have to configure your OAuth redirect_uri to be https://dev.domain.com/flower/login -- that seems to work for me.

hey, no, we ended up going with Basic Auth

Weirdly enough, Basic worked just fine, I figured it was an issue with an url redirect, I might take a look at it again and debug it

Acabei optando pelo mesmo caminho: basic auth. Como estou protegendo a aplicação com uma VPN, tem algum nível de segurança, mas gostaria de utilizar o SSO do Google para prover autenticação.

Fiz o clone do projeto, tentei fazer alguns testes localmente, mas nada fazia com que o template da pagina de login fosse chamado. Algo no meio do caminho impede o redirecionamento correto da rota /login, mas como não sou especialista em Tornado, não consigo dar um veredito sobre o problema.
