tip = require(game.ServerScriptService:FindFirstChild("TrelloAPI"))
local bID = tip:GetBoardID("Ban appeals")
local lID = tip:GetListID("Pending",bID)
script.Parent.MouseButton1Click:Connect(function(player)
tip:AddCard("Feedback Sent.","Sent by: "..player.Name,lID,"","top")
end)
Every time I run the script, it says this error I don't know how to go about this.

FindFirstChild returned false then. Only use FindFirstChild for its return condition. If you need to wait for that module, use WaitForChild.
