Clipboard synchronization does not work on hyprland

[xulongwu4]

I am using hyprland on Solus linux, and launching clipboard-sync results in the following output:

2025-01-14 23:12:17 -  INFO - started clipboard sync manager
2025-01-14 23:12:17 -  INFO - starting clipboard sync
Received an event primary_selection requiring version >= 2 while proxy zwlr_data_control_device_v1@5 is version 1.
2025-01-14 23:12:17 - ERROR - unexpected error while attempting to setup clipboard 1: failed to get wlr clipboard: Wayland compositor communication error
2025-01-14 23:12:17 -  WARN - Issue connecting to some x11 clipboards. This is expected when hooking up to gnome wayland, and not a problem in that context. Details: 'clipboard error: X11 clipboard error : XCB connection error: Connection' for x11 displays: [1..254]

2025-01-14 23:13:39 -  INFO - clipboard updated from display :0
2025-01-14 23:13:57 -  INFO - clipboard updated from display :0

And if I copy something from a wayland window and try to paste it in an xwayland window, it does not work. xclip also does not show the copied content.

Oh, I can add to that: installed the -git and normal variant from aur.

Same issue in Plasma 6.

Edit: it does work if I start clipboard-sync manually, but not with the systemd service.
