I had a similar problem, every time I hit the server, I just got these 2 useless lines of output in the logs.
我遇到了类似的问题，每次我访问服务器时，我都会在日志中得到这 2 行无用的输出。
When I ran:
当我跑：
heroku restart
It ended up showing me more output that let me track down my issue (related to migrating to cedar) (the app was crashing on deploy it appears, never fully starting up, but not showing an error during the deploying process, as would usually occur).
它最终向我展示了更多的输出，让我可以追踪我的问题（与迁移到 cedar 相关）（应用程序在部署时崩溃了，它似乎从未完全启动，但在部署过程中没有显示错误，这通常会发生）。

According to their Developer documentation:
根据他们的开发人员文档：
Check your app's backtrace in the logs to find out what you need to do to fix the problem.
在日志中检查您的应用程序的回溯，以了解您需要做什么来解决问题。

Had a similar problem and the error was masked, running a rails c on heroku gave us the reason for the crash
有一个类似的问题并且错误被掩盖了，在 heroku 上运行 rails c 给了我们崩溃的原因
