findBoardId(): Argument #1 ($id) must be of type int, string given when opening file attachment in card — popup freezes

[dreleex]

Describe the bug
When opening a file attachment inside a Deck card, the card popup expands to fullscreen and freezes. The UI becomes unresponsive and the card cannot be closed without a page reload.

Steps to reproduce

Open a Deck board
Open a card that has a file attachment
Click on the attachment to open it
Card popup freezes and expands fullscreen

Expected behaviour
The file opens normally without the popup freezing.
Actual behaviour
The popup freezes. The following error appears in the Nextcloud log:

TypeError: OCA\Deck\Db\CardMapper::findBoardId(): Argument #1 ($id) must be of type int, string given, called in /var/www/html/nextcloud/apps/deck/lib/Sharing/DeckShareProvider.php on line 984
app: no app in context

Nextcloud version: 33
Deck version: 1.17.0 (latest available for NC 33)
Browser: [Firefox]
OS: macOS

This is also manifesting in the files app. I guess there is a hook in place to find the card that a file might be attached to when files are moved. This same error is preventing me from moving files around.

Following the NC33 upgrade, I am seeing the same error on my side. Are there any known workarounds?

#7761 will fix the type error and make attachments movable again.

The popup view inside cards seems not to be related to this however according to my testing. The file view is still shown if the card is opened in the sidebar and not in the big view. So there's a second issue that makes the file view not render correctly.
