Notifier.php bug? NC Error log

[screenschots]

It works all fine as i can see it but I get this error in the nextcloud log:

Error Exception OC\User\Manager::getDisplayName(): Argument #1 ($uid) must be of type string, null given, called in /var/www/nextcloud/apps/text/lib/Notification/Notifier.php on line 59 in file '/var/www/nextcloud/lib/private/User/Manager.php' line 151

NC 33.0.5
Text 7.0.1
PHP 7.3
MariaDB 11.4

I did update a long way from older version so maybe something stuck from there...

@omnizs38 that's great news, thanks. Just can simpl open a PR, you don't need to get assigned the issue.
