attempt to index field '?' a nil value?

Hi guys. I am making a data system where if I touch a brick it increments the data but it prints nil when clearly it shouldn't.

This is the module script:

local Data = {}
local PlayerData = {} -- player data table


function Data.AddPlayer(player, data) -- adds the player in the table
	PlayerData[player] = data
end


function Data.ReturnData(player) -- returns or gives the player to the script
	return PlayerData[player]
end


function Data.RemovePlayer(player) -- removes player in the table
	PlayerData[player] = nil
end


function Data.IncrementNovas(player, value)
	PlayerData[player]["Novas"] = PlayerData[player]["Novas"] + value
end


function Data.IncrementLevel(player, value)
	PlayerData[player]["Level"] = PlayerData[player]["Level"] + value
end


return Data

This is the script:

local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ServerScriptService = game:GetService("ServerScriptService")
local DataModule = require(ServerScriptService.DataModuleScript)
local ExpGiver = ReplicatedStorage.Resources.Bindables.BindableEvents:WaitForChild("ExpGiverBindableEvent")

local data = {
	Level = 1;
	Novas = 100
}

Players.PlayerAdded:Connect(function(player)
	DataModule.AddPlayer(player, data)
	
	ExpGiver.Event:Connect(function(player, dataname, value)
		if dataname == "Novas" then
			DataModule.IncrementNovas(player, value)
		elseif dataname == "Level" then
			DataModule.IncrementLevel(player, value)
		end
	end)
	
end)

Players.PlayerRemoving:Connect(function(player)
	DataModule.RemovePlayer(player)
end)

And this is the touched script:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local Event = ReplicatedStorage.Resources.Bindables.BindableEvents:WaitForChild("ExpGiverBindableEvent")


script.Parent.Touched:Connect(function(hit)
	-- sees if what touched it is a player
	local player = hit.parent 
	local touched = Players:GetPlayerFromCharacter(player)
	if not touched then return end
	Event:Fire(player, "Level", 1) -- return the player, what value, and the value
end)

but when I touch the brick, the output is:

attempt to index field '?' (a nil value) at line 26 of module script
