Error: EError running notification service: ...opt/nvim-notify/lua/notify/service/buffer/highlights.lua:59: bad argument #2 to 'blend' (no value)

the highlight used for notify because normal is none for me

cmd("autocmd ColorScheme * highlight NotifyBG guibg=#3d3d3d guifg=#3e4451")

code in context

function Make:Report(msg)
    vim.cmd [[packadd nvim-notify]]
    local opt = {
        title = "Neomake"
    }
    local info = vim.g.neomake_hook_context.jobinfo
    local notify = require("notify")
    notify.setup(
        {
            -- Animation style (see below for details)
            stages = "fade",
            -- Default timeout for notifications
            timeout = 3000,
            -- For stages that change opacity this is treated as the highlight behind the window
            background_colour = "NotifyBG",
            -- Icons for the different levels
            icons = {
                ERROR = "",
                WARN = "",
                INFO = "",

                TRACE = "✎"
            }
        }
    )
    if info.exit_code == 0 then
        notify("Job Finished Successfully", _, opt)
    elseif info.exit_code == 1 then
        notify("Job Failed", "error", opt)
    else
        notify("Job Started", "log", opt)
    end
end

With the latest commit as of 10/26/2021, I am still seeing this error. The background_colour highlight group reads like hi NotifyBG guibg=#1a2a31. Why would be that?

Highlight group 'Normal' has no background highlight.

Please provide an RGB hex value or highlight group with a background value for 'background_colour' option

Defaulting to #000000
Error running notification service: ...ged/nvim-notify/lua/notify/service/buffer/highlights.lua:59: bad argument #2 to 'blend' (no value)

After the warning, require("notify.config").background_colour() evaluates to #000000 .

UPDATE: This is because I had hi Normal ... guifg=white and parsing named colors (white) into hex gives a wrong result. Sanity check required -- I will submit a PR soon.
