Angular Ошибка развертывания ssr heroku, как исправить

Question

Я развертываю свое приложение angular (ssr - универсальный) на сервере heroku nodejs, и я получаю эту ошибку:

Ошибка:

(функция ( экспортирует, требует, модуль, __filename, __dirname) {import 'zone.js / dist / zone-node'; 2020-03-15T04: 58: 31.399518 + 00: 00 app [web.1]: ^^^^^^ ^^^^^^^^^^^^^^^^^^ 2020-03-15T04: 58: приложение 31.399519 + 00: 00 [web.1]: 2020-03-15T04: 58: 31.399519 + 00: 00 app [web.1]: SyntaxError: Неожиданная строка

Все работает на моем компьютере, когда я запускаю:

npm run build:ssr
npm run serve:ssr

В чем здесь проблема? Как исправить это?
