In your update function, you need to not execute that code if ActiveWindow returns nil. Something like this will work:

function Test:Update()
  local win = ActiveWindow()
  if win == nil then return end
  ---rest of your function here...
end

 

My job is to make tools you love, with the features you want, and performance you can't live without.
