Kitty displays a strange error when running pywal

[ρƚ4ԋ]

I'm currently on version 0.30.1 of kitty,
and 2 out of 3 times when I execute the following command:
wal --vte -i /path/to/image.png -b "#000000" -a 99 ; eww reload -c /path/to/config/ ; bspc wm -r
I get this error :

@kitty-cmd{"ok\": false, "error": "argument 1 must be dict, not None", "tb": "Traceback (most recent call last):
  File \"/usr/bin/../lib/kitty/kitty/boss.py\", line 704, in _execute_remote_command
    response = handle_cmd(self, window, pcmd, peer_id, self_window)
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I'd be delighted if anyone could help me !
