#41548 seems fixed 👍

[ChristophWurst]

My status changes to the short ooo message once the UserStatusAutomation job ran 👍

The status is reverted when I manually cancel my ooo 👍

[ChristophWurst]

Status changes to dnd when I am outside my working hours 👍

[ChristophWurst]

Code looks sane

DND and OOO automations work as expected

The message field can be nullable from the frontend. Breaks with:

Message: Cannot assign null to property OCA\DAV\Db\Absence::$message of type string in file '/var/www/nextcloud/lib/public/AppFramework/Db/Entity.php' line 136

[ChristophWurst]

The message field can be nullable from the frontend.

#40397 doesn't say anything about optional or required fields, but we need the short message for the status automation and the long one for Mail autoresponders. Let's make them both required. This can be tackled separately, though.

Tested and wörks.

I also tested the "away" bug by following Christoph's steps and it seems to work correctly.
