  1.     }
  3.     private function error(string $message): never
  4.     {
  5.         $this->message($message, 'Error');
  6.         exit(1);
    This line stops the execution flow, without explanation. If this is for debug, you should remove it. If this is to deal with an error, use exceptions instead.
    Time to fix: about 4 hours
