Развертывание Angular 5 на Heroku не удается с ошибкой приложения H10

Я развертываю приложение Angular 5 на Heroku с помощью развертывания Github. Процесс сборки на Heroku завершается успешно. Вот журнал сборки:

Мое приложение никогда не запускается из-за ошибки приложения. Приложение отлично работает локально при использовании npm start или heroku local web.

Вот версии, которые используются в приложении:

• Угловой 5.2.10
• ппм 5.7.1
• узел 9.0.0

Я получаю следующую ошибку и не знаю, как ее исправить:
