【问题描述】：
我正在尝试使用 Heroku 部署我的网站。我使用 Laravel 6 创建了站点。部署进行得很顺利，但是当我尝试打开我的站点时，我收到错误 500。我找不到任何问题，请您指导我找到根本原因并最终解决它吗？

Please don't post screenshots of text。它们无法被搜索或复制，并且可用性差。相反，将代码作为文本直接粘贴到您的问题中。如果选择它并单击
{}按钮或Ctrl+K，则代码块将缩进四个空格，这将导致其呈现为代码。 -
HTTP 500 是一般的服务器端错误消息。它本身并没有告诉我们任何有用的信息。每当您看到这一点时，您的第一步应该是检查您的错误日志以获取更多详细信息。在这种情况下，您似乎需要调试您尝试运行的任何代码以请求
/。至少，向其中添加一些日志记录。 -
我无法调试，因为我无法访问我的网站，我的第一页返回错误 500，我不知道在哪里可以尝试调试。我认为他试图贴上 fichier / 并且我的路由器无法正常工作，所以我没有重定向到我的欢迎页面。我的路由器在本地工作，我迷路了
-
再次，至少，在
/上运行的任何代码中添加一些日志记录。 -
对不起，这是我的第一个网站，我不知道很多东西，我找到了这个日志
