Server script can't find players character in workspace?

I'm using a local script in starterGui to send a players name to a server script using a remote event, everything is working so far, the server script is getting the players name but it can't find the players character in the workspace, It seems like it should and it's probably something really simple I just can't stop, could someone tell me why it won't?

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Remote = ReplicatedStorage:WaitForChild("Remote")


local function Event(player)
	print(player)
	
local PlayerCharacter = game.Workspace:WaitForChild(player)
print(PlayerCharacter)
	
local Headlamp = PlayerCharacter:FindFirstChild("Headlamp")
local LightEmitter = Headlamp:FindFirstChild("LightEmitter")
local Spotlight = LightEmitter:FindFirstChild("SpotLight")

	if Spotlight.Enabled == false then
		Spotlight.Enabled = true
	else
		if Spotlight.Enabled == true then
			Spotlight.Enabled = false
		end
		
end
end

Remote.OnServerEvent:Connect(Event)

It's on line 9
