How to reproduce the issue:

1. Add the following code to your config.

local ruled = require "rules"
local naughty = require "naughty"
local awful = require "awful"

local xresources = require "beautiful.xresources"
local dpi = xresources.apply_dpi
local gears = require "gears"
local rnotification = require "ruled.notification"
local menubar = require "menubar"
local theme = require "beautiful"
local wibox = require "wibox"

naughty.connect_signal("request::display", function(n)
	naughty.layout.box {
		notification = n,
		widget_template = {
			widget = naughty.container.background,
            shape = n.shape,
			{
				widget = wibox.container.margin,
				margins = n.margin,
				{
					layout = wibox.layout.fixed.vertical,
					naughty.widget.title,
					{
						layout = wibox.layout.fixed.horizontal,
						naughty.widget.icon,
						naughty.widget.message,
					},
					naughty.list.actions,
				},
			},
		},
	}
end)

-- Apply theme variables
naughty.config.spacing = dpi(8)
naughty.config.icon_dirs = {
	"/usr/share/icons/Papirus-Dark/",
}
naughty.config.icon_formats = { "svg", "png", "jpg", "gif" }

rnotification.connect_signal("request::rules", function()
	rnotification.append_rule {
		rule = {},
		properties = {
			timeout = 5,
			icon_size = dpi(32),
			max_width = dpi(250),
			ontop = true,
			hover_timeout = 300,
			title = "System Notification Title",
			margin = dpi(16),
			border_width = 0,
			position = "top_right",
            shape = function(cr, w, h)
                gears.debug.dump(w)
            end
		},
	}
	-- Critical notifs
	rnotification.append_rule {
		rule = { urgency = "critical" },
		properties = {
			bg = theme.bg_urgent,
			fg = theme.fg_normal,
		},
	}

	-- Normal notifs
	rnotification.append_rule {
		rule = { urgency = "normal" },
		properties = {
			bg = theme.notification_bg,
			fg = theme.notification_fg,
		},
	}

	-- Low notifs
	rnotification.append_rule {
		rule = { urgency = "low" },
		properties = {
			bg = theme.notification_bg,
			fg = theme.notification_fg,
		},
	}
end)

-- Error handling
naughty.connect_signal("request::display_error", function(message, startup)
	naughty.notification {
		urgency = "critical",
		title = "Oops, an error happened" .. (startup and " during startup!" or "!"),
		message = message,
		app_name = "System Notification",
		icon = theme.awesome_icon,
	}
end)

-- XDG icon lookup
naughty.connect_signal("request::icon", function(n, context, hints)
	if context ~= "app_icon" then
		return
	end
	-- try use application icon
	local path = menubar.utils.lookup_icon(hints.app_icon) or menubar.utils.lookup_icon(hints.app_icon:lower())

	if path then
		n.icon = path
	end
end)

naughty.connect_signal("request::action_icon", function(a, _, hints)
	a.icon = menubar.utils.lookup_icon(hints.id)
end)

2. Send notification via notify-send

Actual result:

This was printed in the stdout:

  table: 0x563abd099260
  border_width : 0 (number)
  position : top_right (string)
  timeout : 5 (number)
  icon_size : 31 (number)
  hover_timeout : 300 (number)
  title : System Notification Title (string)
  max_width : 245 (number)
  shape : function: 0x563abcaded30 (function)
  margin : 16 (number)
  ontop : true (boolean)

Expected result:

Some number corresponding to width should've been printed.
