Request not showing on discord but it says it was sent when it wasn't. Any help?

I am currently working on a mod request system and when I try to send it, it won't show up on discord even though HTTP Requests are Enabled.

Script 1:

--[[
	--// Filename: MainScript.lua
	--// Written By: MacFan2006
	--// Description: The main script of the Mod Request System.
	--// Stealing this code is for babies.
--]]

local FilteringFunction = game.ReplicatedStorage.FilteringFunction
local accused = script.Parent.AccusedUser.Value
local reason = script.Parent.ModJoinReason.Value
local description = script.Parent.Description.Value

local function SendModRequest()
	local request = FilteringFunction:InvokeServer(accused, reason, description)
end

script.Parent.Confirmation.ClickEater.Contents.PromptSendDontSend.SendDontSend.Yes.Activated:Connect(function()
	script.Parent.Confirmation.Visible = false
	script.Parent.SendingPleaseWait.Visible = true
	SendModRequest()
	wait(2)
	script.Parent.SentModRequest.Visible = true
	script.Parent.SendingPleaseWait.Visible = false
end)

Script 2:

--Setup
local webhook = "https://discord.osyr.is/api/webhooks/525516799819776023/qCtpF5eDuHxmf96jG0kv5Xic2p2Q4U7-pOonkPx_sXtjrvtH0t_V2BDZ1XN0KBdWh11F"

--Variables
local filteringFunction = game.ReplicatedStorage.FilteringFunction

--Services
local HTTP = game:GetService("HttpService")

function filteringFunction.OnServerInvoke(player, accused, reason, description)
	local payload = HTTP:JSONEncode({
		content = "Accused User:", accused, "Reason:", reason, "Description:", description,
		username = "Request sent by:" .. player.Name.." - (#"..player.UserId..")"
	})
	
	HTTP:PostAsync(webhook, payload)
	print("Request sent!")
end

Expected Output:

Request Sent!
