      # Logs can come from:
      #
      #   1. Lambda invoke host log: shows cold-start and Jets.boot errors
      #   2. Lambda runtime container log: shows errors inside handler
      #
      # The result seems to hide the cold-start/Jets.boot errors.
      # Guessing AWS does this for security reasons and hides it with {}.
      #
      # Since result["stackTrace"] since only shows errors within the handler.
      # Errors that outside the handler at cold-start/Jets.boot time are not in
      # result["stackTrace"]. They show up in the logs though.
      # So we show the logs that are available from the header.
