Bug logging into https://www.swi-prolog.org/

General
1

Reproduce:

  • Goto swi-prolog site
  • Click login link in page footer
  • click “sign in with “ + Google icon
  • follow Google oauth until successful redirected can to swi

I expected to see the normal swi page I started on, and hopefully ability to comment on pages.

I actually got a 500 error at https://ww1.swi-prolog.org/oauth2/auth_redirect?state=111f…etc…bd0ff&iss=https%3A%2F%2Faccounts.google.com&code=4%2F0…etc…Qg&scope=email+profile+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.profile+openid+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email&authuser=0&prompt=none

And on the visible page body I saw:

Internal server error

Welcome to the forum!

Sorry to hear that.

In trying to reproduce the problem to confirm it is not just you so Jan W. can fix, I was able to successfully log in. This was not the first time I have logged into the site so that may be the factor.

I tried right now and got a similar result as Joseph. As far as I can remember, I had never logged in the site before.
