No hourly change echo "$DESKTOP_SESSION" plasma

[Silesse]

My wallpaper has stopped changing since updating to dwall v3.0
I'm on garuda linux (arch based)

My user's cron job looks like this:
#!/bin/bash
0 * * * * env PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl DISPLAY=:0 DESKTOP_SESSION=plasma DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus" /usr/bin/dwall -s sol

Using the custom image set sol
This works when used through terminal but doesn't seem to trigger every hour

echo "$SHELL | $PATH | $DISPLAY | $DESKTOP_SESSION | $DBUS_SESSION_BUS_ADDRESS | $XDG_RUNTIME_DIR"
Gives me
/bin/bash | /usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl | :0 | plasma | unix:path=/run/user/1000/bus | /run/user/1000

Let me know if there's anything else you need to know. I'd love to get this working again

Changing my user (siva) cron to:
#!/bin/bash
0 * * * * env TERM=xterm-256color PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl DISPLAY=:0 DESKTOP_SESSION=plasma DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus" /usr/bin/dwall -s sol

results in the following from systemctl cronie.service ...

The wallpaper still does not change
Autostart is working just fine

(edit)
Trying to make a systemd service gives me an Invalid environment assignment (ignores /usr/bin/dwall , -s , and sol)
I'm guessing there's another env variable I need? Or maybe I've just typed one wrong and staring at them for so long has driven me crazy...
