Node.js 从Heroku运行应用程序时出错

我在部署到Heroku后尝试运行应用程序时遇到以下错误。由于部署成功，我无法确定错误是什么

如果您登录到heroku，您可以看到项目的日志。。。你的错误很可能就在那里：

你能给我们看一些代码吗？你可以在这里找到我的回购协议：嘿，我发现了错误并进行了更正。但是现在我得到------at=info method=get path=/host=watch-hours.herokuapp.com request_id=e19afb5b-43c4-4bdc-a05b-cf47a32bc6e7 fwd=117.214.91.103 dyno=web.1 connect=0ms service=22ms status=302 bytes=352 protocol=https------没有错误代码。
