Why does this one line stop the script from running properly?

Line 3, where I get the board ID, stops the script from working properly. It allows me to print throughout the script, but the functions itself won't work properly. No errors occur, and nothing happens for these custom admin commands.

local Players = game:GetService("Players")
local API = require(game:GetService("ServerScriptService"):WaitForChild("TrelloAPI"))
local BoardID = API:GetBoardID("622907324")


local Prefix = "%."
local Admins = {
	"AbstractBody"
}

local Commands = {"Kill","Stat","Kick"}	

local function IsAdmin(Player)
	for _,Admin in pairs(Admins) do
		if type(Admin) == "string" and string.lower(Admin) == string.lower(Player.Name) then
			return true
			elseif type(Admin) == "number" and Admin == Player.UserId then
			return true
		end
	end
	return false
end	

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

		for _,Command in pairs(Commands) do
				if string.lower(Arguments[1]) == string.lower(Command) then
				local PlayerInCommand = string.lower(Arguments[2])
				local PlayerCommand = string.lower(Arguments[1])
				
				-- Kill --
				if PlayerCommand == string.lower("Kill") then
					for _,v in pairs(Players:GetChildren()) do
						if string.match(string.lower(v.Name),"^"..PlayerInCommand) then
							local Hum = v.Character:WaitForChild("Humanoid")
							Hum:TakeDamage(Hum.MaxHealth)
						end
					end
				end
				--
				
				-- Change Stat --
				if PlayerCommand == string.lower("Stat") then
					for _,v in pairs(Players:GetChildren()) do
						if string.match(string.lower(v.Name),"^"..PlayerInCommand) then
							if type[Arguments[4]] == "number" then
							local NewStat = Arguments[4]
							local StatChated = Arguments[3]
								local Stat = string.lower(v:WaitForChild("leaderstats"):WaitForChild(string.lower(Arguments[3])))
									if Stat then
										Stat.Value = NewStat
							end
						end
					end
				end
				--
				
				-- Kick Player --
				if PlayerInCommand == string.lower("Kick") then
					for _,v in pairs(Players:GetChildren()) do
						if string.match(string.lower(v.Name),"^"..PlayerInCommand) then
							PlayerInCommand:Kick()
						end
					end
				end
				--
				
				end
			end
		end
	end
end

game.Players.PlayerAdded:Connect(function(Player)
	Player.Chatted:Connect(function(Message,Recipient)
		if not Recipient and IsAdmin(Player) then
			ParseMessage(Player,Message)
		end
	end)
end)
