Ok so, I'm making a mining simulator, and I want to make a tool DataStore. For some reason, the data won't load properly.

Script I used:

001local DataStoreService = game:GetService("DataStoreService")
002local DS = DataStoreService:GetDataStore("MinerzData")
003 
004local function loadData(player)
005    local key = player.UserId .. "-minerzData"
006    local data
007 
008    local success,errorMessage = pcall(function()
009        data = DS:GetAsync(key)
010    end)
011 
012    if success then
013        print('MinerzData | Successfully loaded ' .. player.Name .. "'s data!")
014        return data
015    elseif errorMessage then
016        warn('MinerzData | ' .. errorMessage)
017        return nil
018    end
019end
020 
021local function saveData(player)
022    local key = player.UserId .. "-minerzData"
023    local data = {
024        player.Items.Wood.Value,
025        player.Items.Stone.Value,
026        player.leaderstats.Cash.Value,
027        pickaxes = {
028 
029        }
030    }
031 
032    for i, pickaxe in pairs(player.Backpack:GetChildren()) do
033        if pickaxe:IsA("Tool") then
034            table.insert(data.pickaxes, pickaxe.Name)
035        end
036    end
037 
038 
039 
040    local success,errorMessage = pcall(function()
041        DS:SetAsync(key, data)
042    end)
043 
044    if success then
045        print('MinerzData | Successfully saved ' .. player.Name .. "'s data!")
046        return
047    elseif errorMessage then
048        warn('MinerzData | ' .. errorMessage)
049        return
050    end
051end
052 
053game.Players.PlayerAdded:Connect(function(player)
054    local playerItems = Instance.new("Folder", player)
055    playerItems.Name = "Items"

058    leaderstats.Name = "leaderstats"

060    local cash = Instance.new("IntValue", leaderstats)
061    cash.Name = "Cash"
062    cash.Value = 0
063 
064    for i, item in pairs(game:GetService("ServerStorage"):WaitForChild("Items"):GetChildren()) do
065        local newVal = Instance.new("IntValue", playerItems)
066        newVal.Name = item.Name
067        newVal.Value = 0
068    end
069 
070    local data = loadData(player)
071 
072    if data == nil then
073        warn(player.Name .. " must be a new player; data not found!")
074    elseif data then
075        playerItems:WaitForChild("Wood").Value = data[1]
076        playerItems:WaitForChild("Stone").Value = data[2]
077        cash.Value = data[3]
078        for i, pickaxe in ipairs(data.pickaxes) do
079            local exists = game:GetService("ReplicatedStorage"):WaitForChild("Pickaxes"):FindFirstChild(pickaxe)
080            if exists then
081                local newPick = exists:Clone()
082                local newPick2 = exists:Clone()
083                newPick.Parent = player:WaitForChild("Backpack")
084                newPick2.Parent = player:WaitForChild("StarterGear")
085            end
086        end

On line 78, it errors with:

`1`	`ServerScriptService.InventoryHandler:79: invalid argument #1` `to` `'ipairs'` `(table expected, got` `nil)`

On line 23 I define the "data" table in the saveData() function. I also define "pickaxes" as a sub-table. (line 27) For some reason, when I join the game, it says table expected, got nil. I don't know why this happens, and when I do a print(data.pickaxes), it just prints "nil."

If someone could help, it would mean a lot to me!
