Breaking changes in Nextcloud 21

[ChristophWurst]

Hi there,

I found that your app uses some classes of Nextcloud's third party libraries. Since an upgrade of those for php8 compatibility, your app will have to be adjusted as well. See https://docs.nextcloud.com/server/latest/developer_manual/app_publishing_maintenance/upgrade-guide.html#doctrine-dbal for details. Your app uses Doctrine\DBAL\Types\Type which lost the old contants: https://github.com/doctrine/dbal/blob/3.0.x/UPGRADE.md#deprecated-type-constants.

Cheers

Please note that we just merged a PR with our own constants for the types, so the app can be fully independent of any 3rdparty libraries: nextcloud/server#25089.
