Exception: Argument 1 passed to OC\Core\Controller\LoginController::tryLogin() must be of the type string, null given

[Happyfeet01]

Hello,

i got this error message in Nextcloud.
I can´t reproduce it when i try to login with an unkown user.

Maybe related to the Social App, but i don´t know.

File":"/var/www/nextcloud/core/Controller/LoginController.php","Line":287},"CustomMessage":"--"},"userAgent":"Friendica 'Red Hot Poker' 2020.09-1-1369; https://social.isurf.ca","version":"19.0.3.1","id":"5f7039de46ce8"}

https://social.isurf.ca is an Friendica Site, but i have already disabled the Social App.

Expected behaviour

Maybe an security issue when an Error Message appears.

Actual behaviour

Error Message from Social App?

#21377

I've noticed this suddenly with 20. I had been logging in on a few devices without issue and today I get this error.

What can I do to help debug/triage?

This is without any extra auth, using fennec on Android. I do have totp installed but have tried disabling it.

I should add I do not have the social app installed.

I will post the log shortly.
