Why doesnt the script run when I die? (attempt to call a nil value)

I have a localscript that is inside a player's character. When the player's character dies its supposed to print("Died"), unequip the tool it is holding and fire a remote event. However what happens is that when the character dies, it says attempt to call a nil value. Could someone tell me why it says this?

local plr = game.Players.LocalPlayer
local char = plr.Character
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Attack = ReplicatedStorage:WaitForChild("StarterToolsOnDeath")



if char.Humanoid.Died:Connect() then
	print("Died")
	game.ReplicatedStorage:FindFirstChild("StarterToolsOnDeath"):FireServer(char)
	char.Humanoid:UnequipTools()
end
