ローカルで動作する Rails アプリがあります (でテスト済みbundle exec) が、Heroku (Cedar スタック) でクラッシュしました。ローカルの構成はリモートと同じです (どちらも Postgres を使用しています)。クラッシュは、スタック トレースが Rails/Thin 環境内で発生しているように見えるため、実際にはかなり困惑しています。私のベンダー/プラグインディレクトリには何もないので、非推奨の警告も同様に困惑しています!
Starting process with command `bundle exec thin start -R config.ru -e $RAILS_ENV -p 38427`
