What is a userdata error and how can i fix it?

This is part of my gun drop script, which is supposed to make a gun spawn at the location that you died. However, it does not work as it returns the error

Players.Player.Backpack.MurderGun.ClientGunScript:66: attempt to call field 'Died' (a userdata value)

Here is my code

tool.Unequipped:connect(function(mouse)
	if mouse then	
	mouse.Icon = defaulticon
	end
end)

game.Players.LocalPlayer.Character.Humanoid.Died():connect(function()
	print("Sheriff died")
	local floatinggun = game.ReplicatedStorage.gameplay.Misc.floatinggun
	local newgun = floatinggun:Clone()
	newgun.Position = game.Players.LocalPlayer.Character.Head.CFrame.p
end)

Side note: The code is in a localscript
