This is forbidden?

When a player step on the button it says this..

'Processing PointsSErvice:AwardPoints response, but response is null. userId = 468978, exception is Forbidden Line 29 stack end'

Then the button breaks..

The last print is 'They need to get their points'

local PointsService = Game:GetService("PointsService")
local ting = 0 


function onTouched(hit)

if ting == 0 then 
ting = 1 
print("It got past the tings")
check = hit.Parent:FindFirstChild("Humanoid") 

if check ~= nil then 
print("check is not nil")

local user = game.Players:GetPlayerFromCharacter(hit.Parent) 
local stats = user:findFirstChild("leaderstats") 
local universeBalance = PointsService:GetGamePointBalance(user.userId)

if stats ~= nil then 
print("stats is not nil")
local award = stats:findFirstChild("Awarded")
print("Found total points awarded")
local bought = stats:findFirstChild("Bought")
print("Found total points bought")
local diference = bought.Value - award.Value
print("Found difference")
if award.Value < bought.Value then
print("They need to get their PlayerPoints")
PointsService:AwardPoints(user.userId, diference)
print("Awarded points" .. diference)
if universeBalance ~= award.Value then
print("They are have not got their Points")
bought.Value = awarded.Value
print("Updated bought value")

wait(5)
end
end

ting = 0 
print("Ting back to 0")
end
end
end
end

script.Parent.Touched:connect(onTouched)

You can use this to check if points service is available.

local ps = Game:GetService("PointsService")

local pointsToAward
local s, pointsToAward = pcall(function() return ps:GetAwardablePoints() end)

if s and pointsToAward > 0 then
-- There are points available to give.
else
-- Either there are no more points or the service is unavailable because ROBLOX is updating/fixing.
end
