I keep getting "DataStore request was added to queue" eventhough I'm literally sending 1 request on leave

[gk983 (WifHaver)]

This script works on another game of mine but with different values. I’m just trying to make the options persistent but I can’t. I keep getting this warning and my data cannot be saved:
DataStore request was added to queue. If request queue fills, further requests will be dropped. Try sending fewer requests

local dss = game:GetService("DataStoreService")
local ps = game:GetService("Players")
local http = game:GetService("HttpService")
local rs = game:GetService("ReplicatedStorage")
local settingsEvent = rs:WaitForChild("Settings")

playerClasses = require(rs:WaitForChild("playerClasses"))

local onJoinTable = {
	[true] = function(player, result)
		print("no data was found, player joined for the first time, giving welcome badge.")
		local playerClass = require(script.PlayerClass).new(player)
		playerClasses[ps:GetUserIdFromNameAsync(player.Name)] = playerClass
		print(playerClass)
	end,
	[false] = function(player, result)
		print("Player data was found, loading data.")
		local playerClass = require(script.PlayerClass).new(player, http:JSONDecode(result))
		playerClass:setName(player.Name)
		playerClass:setCharacter(player.Character)
		
		playerClasses[ps:GetUserIdFromNameAsync(player.Name)] = playerClass
		print(playerClass)
	end,
}

local playerClassDB = dss:GetDataStore("_playerClassData")

From what I see, it is more than likely the BindToClose function. Since when playing in studio, or if you’re the only person in the server, it will be saving data for that player twice, since they’re leaving, and the game is shutting down as a result of them leaving, thus triggering the request queue message because the game is saving data for a certain player more than once in less than a second (I could be wrong about it being 1 second. It may be half a second, or even a .1 second time-frame). Hope this helps!

this seems like the reason. thank you so much, I have no idea how I didn’t notice.
