Errors Nextcloud Log

Hello Julien,

In my nextcloud log I can see a lot off errors: Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago Error PHP Undefined index: user at /var/www/html/apps/phonetrack/controller/logcontroller.php#257 an hour ago

I normally log with µlogger and osmand. Logging is not reliable at the moment.

Edit: It is caused by µlogger. If I activate logging I get these errors

What can be the problem?

Best regards, Stefan
