Bug description

Since the upgrade to NC 25, the following error pops up during the execution of cron jobs only at 02:00 and 14:00:

Error: Typed property OCP\BackgroundJob\Job::$time must not be accessed before initialization in /var/www/nextcloud/lib/public/BackgroundJob/TimedJob.php:102
Stack trace:
#0 /var/www/nextcloud/lib/public/BackgroundJob/TimedJob.php(93): OCP\BackgroundJob\TimedJob->start()
#1 /var/www/nextcloud/cron.php(152): OCP\BackgroundJob\TimedJob->execute()
#2 {main}

Steps to reproduce

1. Just have a look to NC journal after 02:00/14:00 cron jobs execution.

Expected behavior

No error ;-)

This looks like a subclass of TimedJob that bypasses the constructor. So far I only found this with the TimedJob from OC, but your trace shows it comes from the TimedJob of OCP.

Could one of you give the result of "occ background-job:list --limit=100" ?

result of "occ background-job:list --limit=100"

Thank you.
Problem seems to be OCA/Files_Antivirus/BackgroundJob/BackgroundScanner.
Can the other confirm you all have the files_antivirus application enabled?

[come-nc]

And it is my fault 😭 nextcloud/files_antivirus@ba33506
