heroku在部署heroku [router]之后立即崩溃：at =错误代码= H10 desc =“应用程序崩溃” method = GET path =“ /”

Question

我的应用在部署后立即崩溃，没有任何错误

这是我的日志

2018-12-10T11:27:10.383418+00:00 heroku[web.1]: State changed from crashed to starting
2018-12-10T11:27:14.130977+00:00 heroku[web.1]: Starting process with command `node index.js`

2018-12-10T11:34:17.613815+00:00 heroku[web.1]: State changed from crashed to down

在发出获取请求后，我收到了此错误

2018-12-10T11:37:04.253584+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=parkinglotapp.herokuapp.com request_id=e37dc0d6-a0a4-4168-987a-e7be6901b0d5 fwd="197.211.56.100" dyno= connect= service= status=503 bytes= protocol=https

我该怎么解决？
