Description of the bug

I've tried making a minimal systemd service for Eww, which runs the daemon:

Restart=on-failure

[Unit]
Description=Eww Daemon
PartOf=graphical-session.target

Inside the script's PATH, I've included the path of every program I'm using inside eww and its related scripts.

Program list, in case you want to take a look

    bc
    bluez
    coreutils
    curl
    eww-wayland
    findutils
    gawk
    gnugrep
    gnused
    hyprland
    jq
    light
    networkmanager
    playerctl
    procps
    ripgrep
    socat
    upower
    wget
    wireplumber
    wofi

Despite all this careful consideration, I still get errors for every deflisten I have in my configuration:, when run in the systemd service:

ERROR eww::script_var_handler > [crates/eww/src/script_var_handler.rs:236] Error while Executing listen var-command playerctl -F metadata title || true: No such file or directory (os error 2)

I've checked and double-checked the program list in PATH, but couldn't find anything that may have slipped.

Reproducing the issue

1. Have a configuration that makes use of deflisten variables
2. Try running it in a systemd service
3. Check journalctl --user -eu eww

Expected behaviour

The deflisten variables get updated properly, as it's being done when run outside the service.

Additional context

My dotfiles with pending Eww config changes: https://github.com/fufexan/dotfiles/tree/eww-deflisten

Seems like you're missing sh in the PATH, no?

As far as I can tell, everything's working properly now. So I think that was it. Thanks and sorry for bothering!
