qBittorrent & operating system versions

qBittorrent: v5.1.2 WebUI (64-bit) from lscr.io/linuxserver/qbittorrent:latest
Operating system: Linux df8de3c2647a 6.12.34+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.34-1+rpt1~bookworm (2025-06-26) aarch64 GNU/Linux
Qt: 6.9.1
Libtorrent: 2.0.11.0
Boost: 1.84.0
OpenSSL: 3.5.2
zlib: 1.3.1

What is the problem?

I have a Python script checking file extensions in added torrents (magnets) that has been working, but sometime in the past few months it has silently stopped working.

Previously the API call (client.torrents_files(hash=torrent.hash)) has returned a file list as expected, but didn't anymore until I added a sleep() before requesting the file list to allow time for metadata download.

I tried adding "%C" (number of files) to the external script call which passes -1, presumably because the metadata is missing.

Thanks in advance for any pointers on this, hope I'm not missing anything obvious.

Steps to reproduce

Add a script to "Run on torrent added" that requests the torrent file list.
The file list is empty.
Try the script again, but with an added sleep() that allows for the metadata to download.
The file list is populated.
