Light/Dark mode toggle is not working

[muddi900]

I am trying to add dark mode to a site. This is the theme-block for the yaml file:

theme:
  name: material
  pallette:
    - media: "(prefers-color-scheme: light)"
      scheme: default 
      toggle:
        icon: material/brightness-7
        name: Switch to dark mode
    - media: "(prefers-color-scheme)"
      toggle:
        icon: material/brightness-auto
        name: Switch to light mode

    - media: "(prefers-color-scheme: dark)"
      scheme: slate
      toggle:
        icon: material/brightness-4
        name: Switch to system preference

It is not working:

What may be causing this?

You have a typo in "palette".

If you are using an editor that supports this, turning on configuration validation and auto-complete can be very useful.
