Having &prompt=login in OAuth2 url leads to 500 if logged out

[BananaJeanss]

If logged in, works fine and shows the authentication prompt again. However, if the user is logged out, shows a 500 instead of the log in form.

URL (when the &prompt=login is removed, works fine): https://auth.hackclub.com/oauth/authorize?client_id=0b9e9bf923d2323c16de10e504f5f153&redirect_uri=https://goship.dino.icu/auth/callback&response_type=code&scope=openid+profile+email+name+profile+slack_id+verification_status&prompt=login
