Describe the bug
I try to get the attachments from a card, while attachmentCount is for example 3, list of attachments is empty.

To Reproduce
Steps to reproduce the behavior:

1. Create a card
2. Attach a file from nextcloud
3. Attachment is listed in browser
4. check API endpoint GET /boards/{boardId}/stacks/{stackId}/cards/{cardId} - attachmentCount is the count of attachments, attachments is an empty list
5. check API endpoint GET /boards/{boardId}/stacks/{stackId}/cards/{cardId}/attachments - empty list

Expected behavior
see a list of attachments or the fileId or a download-link
