why cannot i load a sound through soundid?

I am trying to do a plugin when you can play sounds and i am up to the step to load the sounds. when i enter "rbxassetid://1238092370", it says 17:55:52.113 - Error: cannot load music!. What do I do?

		script.Parent.Sound.SoundId = script.Parent.Tune.Value
			
			local sound = script.Parent.Sound
			if not sound.IsLoaded then
	wait(5)
if not sound.IsLoaded then
	warn("Error: cannot load music!")
else
	print("music loaded!")
end
			else
				print("music loaded!")
			end
