Heroku: at=error code=H10 desc="App crashed" method=GET path="/"

Question

我尝试部署我的 Vaadin Springboot 应用程序，它在 localhost 上运行良好，但是当尝试使用 heroku 部署它时，我一直收到 H10 错误代码。

这是heroku错误日志

我在stackoverflow上没有找到任何答案，这可以解决我的问题。

Answer 1

您正在使用 Spring Boot 并且不需要 webapp-runner！

请阅读文档： https ://devcenter.heroku.com/articles/deploying-spring-boot-apps-to-heroku
