Steps to reproduce:

Have a large photo folder in Nextcloud (/Fotos with ~17,000 files, JPG/PNG).

Upload new photos from iOS.

Open the Nextcloud iOS app (version 7.1.2) and go to:

Menu → Uploaded media → remains empty

Browse → Fotos folder → only today’s 4 files are shown, although thousands exist.

On the server side, Nextcloud logs the following error when the iOS app requests the folder listing:
pack() expects at least 1 argument, 0 given

Expected behaviour:

iOS app should list all files in the folder /Fotos and display “Uploaded media” content.

No pack() error on the server.

Actual behaviour

Only 4 newest images are shown in the app.

“Uploaded media” view stays empty.

Server log shows SabreDAV error:
pack() expects at least 1 argument, 0 given /app/www/public/3rdparty/sabre/dav/lib/DAV/PropFind.php line 95

Logs

If applicable, you can post the iOS app or server logs (removing any sensitive information).

Reasoning or why should it be changed/implemented?

Environment data

Nextcloud Server: 31.0.8.1 (Docker)

Nextcloud iOS App: 7.1.2 (iOS 17.x)

User storage: ~17k photo files in one folder (/Fotos)

Web server: Apache, nginx

Database:

PHP version:

Nextcloud version: see Nextcloud admin page

Start by reproducing the large-folder listing and empty “Uploaded media” behavior with the stated Nextcloud Server and iOS app versions. Inspect the server error at 3rdparty/sabre/dav/lib/DAV/PropFind.php line 95 alongside the iOS folder-listing flow; done means all files and uploaded media appear without the pack() error.
