(Solved) humanoid.Died not firing whatsoever?

I want to destroy an NPC whenever they die, but I just can't seem to get this to work. No output errors, only print("test") shows in output.

Screenshot of my pathing

Code (Server script parented under Enemy's model named "EnemyDeath")

local humanoid = script.Parent:WaitForChild("Humanoid")
local RunService = game:GetService("RunService")
print("test")

RunService.Heartbeat:Connect(function(deltaTime)
    humanoid.Died:connect(function()
        humanoid.Parent:Destroy()
        print("destroy!")
    end)
end)
