Infinite Yield Possible at ServerScriptService?

Hello! I am trying to make a localscript that sends a card to a trello board, I thought I had my code correct but for some reason it doesn't work fully. I have a feeling that it stops at local TrelloAPI = require(game:GetService('ServerScriptService'):WaitForChild("TrelloAPI"));

I believe this because it gives the following error: https://gyazo.com/dc67137a28174b54c486a6a2426b7dc5

Here is my code..

local name = script.Parent.NameBox;
local reason = script.Parent.ReasonBox;

script.Parent.send.MouseButton1Click:connect (function()
	local TrelloAPI = require(game:GetService('ServerScriptService'):WaitForChild("TrelloAPI"));
	local BoardID = TrelloAPI:GetBoardID("Inactivity");
	local ListID = TrelloAPI:GetListID("Notices",BoardID)
	local NewCard = TrelloAPI:AddCard("Inactivity Notice Incoming...","Notice from:"..name"\n Reason:"..reason"",ListID)
	wait(5)
	game.Players.LocalPlayer:kick("Sent!")
end)
