DataStore not working and no error? Not a local script

local DataStoreService = game:GetService("DataStoreService")
local DataStore1 = DataStoreService:GetDataStore("DataStore1")

game.Players.PlayerAdded:Connect(function(player)
    local PlayerUserId = "Player_"..player.UserId
    local leaderstats = Instance.new("Folder", player)
    leaderstats.Name = "leaderstats"
    local Credits = Instance.new("IntValue", leaderstats)
    Credits.Name = "Credits"
    local Research = Instance.new("IntValue", leaderstats)
    Research.Name = "Research"
    --Load Data
    
    local data
    local success, errormessage = pcall(function()
        data = DataStore1:GetAsync(PlayerUserId)
    end)
    if data ~= nil and success then
            data[Credits.Value] = Credits.Value
            data[Research.Value] = Research.Value
		print("21")
	elseif data == nil and success then
            data[Credits.Value] = 500
            data[Research.Value] = 10--setting it to the default amount if they dont have date
		end
    end)
	print("27")
game.Players.PlayerRemoving:Connect(function(player)
    local PlayerUserId = "Player_"..player.UserId
    print("30")
	local data = {}
    for i, v in pairs(player.leaderstats:GetChildren())do
        table.insert(data, v.value)
    end
	print("34")
    
    local success, errormessage = pcall(function()
        DataStore1:SetAsync(PlayerUserId,data)        
    end)
    
    if success then
        print("Data Successfully Saved")
    
    else
        print("There was an error saving data")
        warn(errormessage)
    
    end
end)

The problem might lie in lines between 27 and 34 which don't print the numbers
