Highlight group NotifyBackground has no background highlight.

[vinoff]

I am getting the following warning:

   Warn  10:51:25 notify.warn nvim-notify Highlight group 'NotifyBackground' has no background highlight
Please provide an RGB hex value or highlight group with a background value for 'background_colour' option.
This is the colour that will be used for 100% transparency.
\```lua
require("notify").setup({
  background_colour = "#000000",
})
\```
Defaulting to #000000

It started when I started using Dracula. Is it something on my side? I am using Noice (which has notify has a dependency).

EDIT: Setting transparency to False fixed this.
