[ERROR] Your Worker failed validation because it exceeded startup limits.

  To ensure fast responses, there are constraints on Worker startup, such as how much CPU it can
  use, or how long it can take. Your Worker has hit one of these startup limits. Try reducing the
  amount of work done during startup (outside the event handler), either by removing code or
  relocating it inside the event handler.
