Waybar does not display hyprland/workspaces module

[liam-gleason-snhu]

Hyprland: v0.29.1-1, Waybar: v0.10.0-1
Relevant bits of the Waybar config:

...
    "modules-left": ["hyprland/workspaces"],
...
    "hyprland/workspaces": {
        "format": "{id}",
        "disable-scroll": true,
    },
...

When starting Waybar I get the warning:
[warning] module hyprland/workspaces: Disabling module "hyprland/workspaces", Error parsing JSON: * Line 1, Column 1 Syntax error: value, object or array expected.

Your version of Hyprland is very old, from September 2023, in fact. Please upgrade it to at least version 0.35 and try again

The error persists even with the latest Hyprland and Waybar
