Admin Script not working at all and doesn't print any errors?

Hello, I've been recently working on an Admin Script that has worked fine until I added the Trello API to it, it's a Server Script located in ServerScriptService. I don't know what the issue is as it's printing nothing to show any sign of errors or warnings.

local ReplicatedStorage = game:WaitForChild("ReplicatedStorage")
local kick = Instance.new("RemoteFunction", ReplicatedStorage)

local API = require(game:GetService("ServerScriptService"):WaitForChild("TrelloAPI"))
local BoardID = API:GetBoardID("Game: Inspired Bans")
local ListID = API:GetListID("Bans", BoardID)
local Banned = API:GetCardsInList(ListID)

local Admins = {
	{
		GroupId = 2969540;
		RankId = 248;
	};
}

local Prefix = "\\"
local Players = game:GetService("Players")
local Commands = {}

Commands.kick = function(Sender, Arguments)
	local Message = table.concat(Arguments, " ")
	if (Arguments == nil) then return end
	local Victim = Arguments[1];
	if Victim == "me" then
		Victim = Sender.Name
	end
	local Reason = Arguments[2];
	if (Arguments[2] == nil) then
		Reason = "No reason provided."
	end
	game:GetService("Players"):FindFirstChild(Victim):Kick(Reason)
end

Commands.ban = function(Sender, Arguments)
	local Message = table.concat(Arguments, " ")
	if (Arguments == nil) then return end
	local Victim = Arguments[1];
	if (Arguments[1] == nil) then return end
	local Reason = Arguments[2];
	if (Arguments[2] == nil) then
		Reason = "No reason provided."
	end
	game:GetService("Players"):FindFirstChild(Victim):Kick("You have been banned.")
	local NewCard = API:AddCard(Victim,Reason,ListID)
	NewCard()
end

Commands.speed = function(Sender, Arguments)
	local Message = table.concat(Arguments, " ")
	if (Arguments == nil) then return end
	local Victim = Arguments[1];
	if Victim == "me" then
		Victim = Sender.Name
	end
	local Speed = tonumber(Arguments[2]);
	if (Arguments[2] == nil) then
		Speed = 16
	end
	game:GetService("Players"):FindFirstChild(Victim).Character.Humanoid.WalkSpeed = Speed
end

local function checkBanned(name)
	local isBanned = false
	for i, v in pairs(Banned) do
		if v.name == name then
			isBanned = true
		end
	end
	return isBanned
end

local function IsAdmin(Player)
	for _, Admin in pairs (Admins) do
		print(Admin, Player)
		if type(Admin) == "table" then
			local Rank = Player:GetRankInGroup(Admin.GroupId)
			if Rank >= (Admin.RankId or 248) then
				return true
			end
		end
	end
	return false
end

local function ParseMessage(Player, Message)
	local PrefixMatch = string.match(Message, "^"..Prefix)
	if PrefixMatch then
		Message = string.gsub(Message, PrefixMatch, "", 1)
		local Arguments = {}
		
		for Argument in string.gmatch(Message, "[^%s]+") do
			table.insert(Arguments, Argument)
		end
		
		local CommandName = Arguments[1]
		table.remove(Arguments, 1)
		local CommandFunc = Commands[CommandName]
		
		if CommandFunc ~= nil then
			CommandFunc(Player, Arguments)
		end
	end
end

Players.PlayerAdded:Connect(function(Player)
	if checkBanned(Player.Name) then
		game:GetService("Players"):FindFirstChild(Player.Name):Kick("You have been banned.")
	end
	Player.Chatted:Connect(function(Message, Recipient)
		if not Recipient and IsAdmin(Player) then
			ParseMessage(Player, Message)
		end
	end)
end)

This is the full script because I don't know where the issue is contained.
