i cant save a player data. how to fix?

i try to save a player userid whenever a player try to exploiting, so i can store his id at datastore

local data = game:GetService("DataStoreService")
local banList = data:GetDataStore("banList")
game.Players.PlayerAdded:Connect(function(player)
    local userid = player.UserId
    player.CharacterAdded:Connect(function(character)
        local humanoid = character:WaitForChild("HumanoidRootPart")
        humanoid.ChildAdded:Connect(function(object)
            if object.ClassName == "BodyGyro" or object.ClassName == "BodyPosition" or object.ClassName == "BodyVelocity" then
                object:Destroy()
                local success, errormessage = pcall(function()
                    banList:SetAsync(userid, true)
                end)
                if success then
                    print("Ban saved!")
                end
                player:Kick("Jangan Ngecit Dongg !!")
            end
        end)
    end)
end)

and this is the different script i have

local DataStoreService = game:GetService("DataStoreService")
local banList = DataStoreService:GetDataStore("banList")
local manual = {}
game.Players.PlayerAdded:Connect(function(player)

    local userid = player.UserId
    if manual[userid] then
        player:Kick("KEBAN KAU ANJIM !!")
    end
    local banned
    local success, errormessage = pcall(function()
        banned = banList:GetAsync(userid)
    end)
    if banned == true then
        player:Kick("KEBAN KAU ANJIM !!")
        print("Mamamm")
    end
end)

but this script is not working, how do i fix it what is wrong with the script?
