Why is "local clone a nil value" in my script?

script.Parent.Touched:connect(function(charTouched)
	local character = charTouched.Parent --character
	local player = game.Players:GetPlayerFromCharacter(character) --player
	local clone = character:Clone()
	
	clone.Parent = game.Lighting
	character:Destroy()
	
	wait(2)
	
	clone.Parent = game.Workspace	
	character = clone
	
end)

I'm attempting to clone the player's character, store it in lighting, then destroy its current character. After 2 seconds, the clone goes into game.Workspace and then the character is set to clone. However, it states on line 6 that the variable for clone is a nil value. Why is this?
