angular 6 до 8, angular универсальный, Произошло необработанное исключение: конфигурация «производство» не задана в рабочей области

Question

Я пытаюсь обновить angular версию и заново установить sh новую версию angular universal.

Angular универсальный insatall:

ng add @nguniversal/express-engine --clientProject [project name]

Bulid project

npm run build:ssr && npm run serve:ssr

пакет. json

"serve:ssr": "node dist/server/main.js",
"build:ssr": "ng build --prod && ng run [project name]:server:production",

Сообщение об ошибке:

An unhandled exception occurred: Configuration 'production' is not set in the workspace.

Я попытался , удалив команду --prod, но он все еще не работает

Ниже мой angular.json файл:

[project-name]: название моего проекта.

[a sequence]: последовательность автоматически сгенерированных последовательностей.
