Heroku[路由器]：at=错误代码=H10 desc=“应用程序崩溃”方法=GET路径=/favicon.ico”

Question

Heroku[路由器]：at=错误代码=H10 desc=“应用程序崩溃”方法=GET路径=/favicon.ico”

Sau*_*ood 6 heroku node.js reactjs mern heroku-cli

我有一个简单的 MERN 应用程序，在本地主机上运行良好，但是当我将其部署到 Heroku 时，我看到一个页面出现以下错误：

应用程序错误应用程序中发生错误，无法提供您的页面。如果您是应用程序所有者，请检查您的日志以了解详细信息。您可以使用以下命令从 Heroku CLI 执行此操作 heroku logs --tail

控制台显示如下：Failed to load resource: the server responded with a status of 503 (Service Unavailable)

还附上了一张图片！

下面还给出了 Heroku 日志......

我是 MERN Dev 的新手，所以无法真正弄清楚问题到底是什么，Heroku 日志也没有多大帮助，请帮助我！
