Question

我在5个月前设置了这个超级简单的rails应用程序，直到最近才开始工作。

但是今天我注意到我得到了这个错误：“我们很抱歉，但出了点问题。如果您是应用程序所有者，请查看日志以获取更多信息。”

我检查了heroku日志，但我没有看到任何错误，我假设是每天重启：

我还看了一下我的production.log文件，但它很奇怪。

我对如何解决这个问题感到茫然。有什么建议吗？

Answer 1

因此，事实证明它实际上与环境无关。

我使用prod env在我的机器上运行了该站点，并且能够找到access_token已过期，错误未正确捕获导致500错误。我修复了它并重新部署了网站。它现在有效。

Heroku rails安装在月后停止工作
