最近注意到我的Heroku应用程序被标记为“欺骗性站点”，我认为我将尝试重新部署它以解决此问题。我做了heroku destroy + heroku create在Heroku上重新部署了该应用。然而。我收到代码H10错误，并且在检查heroku logs --tail信息后不知道要怎么解决。我的应用在localhost：3000上运行良好。
我尝试了heroku restart并且还运行了rake db:migrate，这些命令都运行了，没有任何错误，但是该应用仍然在网站上显示错误。
已编辑： 我想补充一点，当我在根目录终端中输入 heroku run bundle exec rails db：seed 时遇到这些错误
以下是我通过heroku运行包exec rails db：seed --trace：所获取的日志：

我将需要更多信息，以指出您的代码到底出了什么问题。看来您的堆栈跟踪实际上已被切断。您可以通过运行heroku logs -n=1500拉更长的日志片段。
