--replaces-process throws exception in multiprocessing

[GregPK]

Script runs fine in all other cases, but running with --replaces-process on my machine like so:

notify-send.py --replaces-process testrep "Test replaces"

causes:

Traceback (most recent call last):

Same issue here on arch too.
Python 3.11.6
Installed notify-send.py through AUR where notify-send-py has Version: 1.2.7-1

Unfortunately I don't have time to work on a fix, currently. But PR is always welcome

[Qu4tro]

This is fixed on main actually. It just needs a new release.

[vincentaxhe]

notify-send is capable of replace id now, as long as in a loop.
use -p to emit id, -r to replace id. I give up using notify-send.py with my deadd-notification, only volume notification is not ideal。

Thank you so much, I was pulling my hair out over this
