Nodejs экспресс-маршруты не могут вставить mysql в POST

Я хочу добавить код в базу данных из HTML-формы экспресс-маршрута. Форма работает, отслеживание и номер офиса Sanitized правильно выводятся на консоль из пользовательского ввода, но вызов базы данных не завершается.

Любая идея, почему БД не вызывается, когда POST инициируется с экспресс-маршрута?
