Error processing request URL GET /Items//playbacki

[PyL96]

Hello,

My Jellyfin.log keep getting spammed with the same error and I wonder why. I think it can be the cause of some of the issue encountered by my users.

My setup is:
Jellyfin 10.8.13
Installed via debian apt repo
Debian 12 x64 running in a Proxmox LXC

The logs that keep getting spammed, 1762 times in 2 hours (The item ID are not the same every time):

Code:

Jellyfin is behind Nginx on the same VLAN:

Do you have any ideas ?
