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
