DataStore request was added to queue?

I made this script for my Ban GUI

local ReplicatedSorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local DataStoreService = game:GetService("DataStoreService")
local GetDataStore = DataStoreService:GetDataStore("BanUser")

local BanPlayer = ReplicatedSorage:WaitForChild("BanPlayer")
local Settings = require(ReplicatedSorage:WaitForChild("Setting"))

local DataStoreSuccess = {}
local Banned = {}

Players.PlayerAdded:Connect(function(Player)
	local Success,Res = pcall(function()
		return GetDataStore:GetAsync(Player.UserId)
	end)
	
	if not (Success) then
		DataStoreSuccess[Player.UserId] = false
		Player:Kick("DataStoreFailed")
	end
	
	if (Success and Res) then
		Banned[Player.UserId] = true
		Player:Kick("You are Banned")
	end
end)

Players.PlayerRemoving:Connect(function(Player)
	if (DataStoreSuccess[Player.UserId] == false) then
		DataStoreSuccess[Player.UserId] = nil
		Banned[Player.UserId] = nil
	end
	
	if(Banned[Player.UserId]) then
		return
	end
end)

BanPlayer.OnServerInvoke = function(Admin,Type,UserString)
	if not (Settings)[Admin.UserId] then
		return "You are not an admin!"
	end
	
	local UserId
	
	if (tonumber(UserString)) then
		UserId = tonumber(UserString)
	elseif (tostring(UserString)) then
		local Success,Res = pcall(function()
			return Players:GetUserIdFromNameAsync(UserString)
		end) 
		
		if Res and Success then
			UserId = Res
		end
	end
	
	if not(UserId) then
		return "Player does not exist"
	end
		
	local Success,Res = pcall(function()
		GetDataStore:SetAsync(UserId,Type)
	end)
	
	if (Success) then
		return "Player Has been Banned"
	else
		return Res
	end
end

And then I did this script to go inside the ScreenGUI

wait(1 + math.random())

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ContextActionService = game:GetService("ContextActionService")
local Players = game:GetService("Players")
local LocalPlayer = Players.LocalPlayer
local Admins = require(ReplicatedStorage.Setting)
local BanPlayer = ReplicatedStorage.BanPlayer
local Sp = script.Parent
local Main = Sp.Frame
local Ban = Main.Ban
local Unban = Main.Unban
local User = Main.User
local Error = Main.Error

function BanUser(Type)
	local Message = BanPlayer:InvokeServer(Type,User.Text)
	
	if (Message) then
		Error.Visible = true
		Error.Text = Message
		wait(3)
		Error.Visible = false
	end
end

Ban.MouseButton1Down:Connect(function()
	BanUser(true)
end)

Unban.MouseButton1Down:Connect(function()
	BanUser(false)
end)


function Visibility()
	if not (Admins[LocalPlayer.UserId]) then
		return
	end
	Main.Visible = not Main.Visible
end

LocalPlayer.Chatted:Connect(function(Message)
	if (string.lower(Message) ==  "/bpanel") then
		Visibility()
	end
end)

ContextActionService:BindAction("BanFrameVisiblity", function(InputName, InputStats, InputKeys)
		if (InputStats == Enum.UserInputState.Begin) then
				Visibility()
		end
	end,false,Enum.KeyCode.E,Enum.KeyCode.ButtonA)

The issue is that an error keeps coming up saying "DataStore request was added to queue. If request queue fills, further requests will be dropped. Try sending fewer requests.Key = 45059373" and I don't know how to fix this or even what the issue is. This happens when I try to ban someone.
