DataStore signalling script error?

local DataStore = game:GetService("DataStoreService")
local AS = DataStore:GetDataStore("AS")


game.Players.PlayerAdded:connect(function(player)
    local PA = player.PlayerGui:WaitForChild("Main")
    local PB = PA:WaitForChild("AttributesFrame")
    local PC = PB:WaitForChild("UpgradePoints")
    local points = PC
     points.Value = AS:GetAsync(player.UserId) or 0 -- gives error 502: API Services rejected request with error: HTTP 0 (HTTP 403 (HTTP/1.1 403 Forbidden))
     AS:SetAsync(player.UserId, points.Value)
    points.Changed:connect(function()
  AS:SetAsync(player.UserId, points.Value)
     end)
    print(points.Value)
end)

game.Players.PlayerRemoving:connect(function(player)
 AS:SetAsync(player.UserId, player.points.Value)
end)

error: 502: API Services rejected request with error: HTTP 0 (HTTP 403 (HTTP/1.1 403 Forbidden))

I don't have any idea what is wrong, I used almost the same code somewhere else and it worked there
