DataStore not functioning?

Hi guys, I am trying to use DataStores in my new game but when I go to test them, the values don't load and I'm not sure why they aren't loading. I did have an error before I made a tiny amendment to the script, it said:

EDIT: I now keep getting this error. It occurs on the lines where the asynchronous methods of the data store are used (Line 16 and line 89 is where I started getting these errors, it alternates between the two randomly.)

HTTP 403 (HTTP/1.1 403 XSRF Token Validation Failed)

Now it does not show anything in the output and I'm not sure how to fix the script. Any help is appreciated, thanks!

Script (EDITED, found out why it wasn't functioning at all but now it won't progress through the clearAllValues function as it throws the token validation error above after the "if ds ~= nil then" line):

math.randomseed(tick())

rs = game:GetService("ReplicatedStorage")

function clearAllValues(item,ds,plr)
    for i,v in pairs(item:GetChildren()) do
        if not v:IsA("Folder") then
            v:Destroy()
        end
        clearAllValues(v,ds,plr)
        if v.Parent ~= plr.Accessories then
            local hasGot = Instance.new("BoolValue")
            hasGot.Name = "HasGotItem"
            hasGot.Parent = v
            if ds ~= nil then
                hasGot.Value = (ds:GetAsync(hasGot.Parent.Name.."HasGot") ~= nil) and ds:GetAsync(hasGot.Parent.Name.."HasGot") or false
