ScheduledActions and Maintenance tasks return errors

Hi!

On my dev installation I have two tasks: ScheduledActions and Maintenance (I don't see them on my production forum):

I tried to run them manually, but got an error:

RuntimeException:  (0)
#0 /home/vagrant/Code/ips4.site.com/system/Patterns/ActiveRecord.php(121): IPS\_Task::constructFromData(Array)
#1 /home/vagrant/Code/ips4.site.com/applications/core/modules/admin/settings/advanced.php(556): IPS\Patterns\_ActiveRecord::load('154')
#2 /home/vagrant/Code/ips4.site.com/system/Dispatcher/Controller.php(86): IPS\core\modules\admin\settings\_advanced->runTask()
#3 /home/vagrant/Code/ips4.site.com/applications/core/modules/admin/settings/advanced.php(35): IPS\Dispatcher\_Controller->execute()
#4 /home/vagrant/Code/ips4.site.com/system/Dispatcher/Dispatcher.php(129): IPS\core\modules\admin\settings\_advanced->execute()
#5 /home/vagrant/Code/ips4.site.com/admin/index.php(14): IPS\_Dispatcher->run()
#6 {main}

What does it mean, and how to fix it? All plugins and customizations are disabled. Cache is cleared.
