  puts "    WARN: handler for it could not be found. The default fallback handler is being used.\n    The default fallback handler simply prints out the event payload for debugging, it will be printed below.\n    Usually the default handler is not what you want.\n    You might be using a test event payload for testing which does not represent a real event.\n    Please double check the event payload.\n  EOL\n  if ENV[\"_HANDLER\"] # on AWS Lambda\n    puts \"event: \#{JSON.dump(event)}\"\n  else\n    puts \"event:\"\n    puts JSON.pretty_generate(event)\n  end\n\n  if target\n    puts \"WARN: Event handler target not found: \#{target}\".color(:red)\n    target_class, target_method = target.split(\".\")\n    target_class = target_class.camelize\n    target_method ||= \"perform\"\n    puts <<~EOL\n      You can configure define an app/events handler in your application.
