尽管正确部署了Spring Boot和Angular应用程序（两者分别部署），但heroku仍然显示应用程序错误，尽管它显示构建成功

Question

我创建了一个弹簧靴和有角度的应用程序  并按照编写的正确步骤部署在Heroku上

https://www.callicoder.com/deploy-host-spring-boot-apps-on-heroku/

https://www.codemeals.com/angular/deploy-angular-7-app-to-heroku/

尽管构建成功，但仍无法提供我的应用程序。  你有什么主意吗？

两种情况下的应用程序错误

An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail ```
