Looks like a bug in the dav app. A quick glance suggests that the `beforeDelete()` method in [server/ChunkingV2Plugin.php at master · nextcloud/server · GitHub](https://github.com/nextcloud/server/blob/master/apps/dav/lib/Upload/ChunkingV2Plugin.php) is missing a call to `$this->checkPrerequisites();` (which the other three “before” and “after” methods has in them). When `getUploadStorage()` is called in that function, there’s a missing value and the error occurs.

I think you should open an issue at [Issues · nextcloud/server · GitHub](https://github.com/nextcloud/server/issues) . I didn’t find an existing one.
