TYPO3 Core

Steps to reproduce:

1. create a new scheduler task, save & exit
2. edit the newly created task and click on the "Delete" button

Stack dumps, shortened:

(1/1) TypeError
TYPO3\CMS\Scheduler\SchedulerManagementAction::tryFrom(): Argument #1 ($value) must be of type string, array given
in /var/www/html/typo3/sysext/scheduler/Classes/Controller/SchedulerModuleController.php line 180
...
$queryAction = SchedulerManagementAction::tryFrom($queryParams['action'] ?? '') ?? SchedulerManagementAction::LIST;

at TYPO3\CMS\Scheduler\SchedulerManagementAction::tryFrom(array('delete' => '8'))

The scheduler task can be removed normally in the list view of the scheduler module.
