When moderator is trying to open timeline of this question, system redirects to the error page.

enter image description here

But regular members can open it.

  • what browser and OS? Have you tried to open timeline from the same browser/OS using incognito/private mode (which reproduces how it would work for a user that is not logged in)?

    @gnat, Chrome in Win 10. Why do you think browser is important for server-side error?

    @Qwertiy the browser might not support certain things that are crucial, e.g. it might ignore/omit the fkey parameter, not store session cookie properly etc, which can lead to internal server error. In this case looks like the error is indeed purely server side, but always worth checking the client first. Mar 5, 2020 at 11:14

    I have repro'd this and have found the exception, I'll ping the devs about it.

  • This... doesn't seem related to a single question.

A change went out that mistakenly prevented the Community user from being fetched from the DB. Since we assign flags and (occasionally) votes to the Community user in various cases (e.g. when a real user is deleted)... that causes a bit of a problem. :)

The fix is out in production. Thanks for the report!
