sever script cannot find what_failed string value? [SOLVED]

i am making several loading screens and i want the game to use data stores to remember what one the player selected

if it can't find the data then it should display an error

but i get error attempt to index nil with what_failed

the script is in game > workspace > data_store_folder > DSS_script

what failed is in player's character

DSS_script:

local DSS = game:GetService("DataStoreService")

function new_player(player)
    --getting the load screen number
    local player_gui = player.PlayerGui
    local loading_type_store = game:GetService("DataStoreService"):GetDataStore("loading_type")
    local player_id = player.UserId
    local character = player.Character
    local wf_copy = character.what_failed:Clone()
    local loading_type_value = character.load_screen_selected
    local loading_type
    local success, err = pcall(function()
        loading_type = loading_type_store:GetAsync(player_id)
    end)
    if success then
        loading_type_value.Value = loading_type
        character.load_screen_selected.Parent = character.load_screen
        character.loading_screen.Parent = player_gui
    else
        warn("could not retrieve data")
        character.what_failed.Value = "getting load screen number"
        wf_copy.Parent = player_gui
    end


end

game.Players.PlayerAdded:Connect(new_player)
