ActionController :: RoutingError "/ cloudfoundryapplication"の[GET]と[OPTION]と一致するルートはありません

Question

Pivotal Web ServicesでPumaを使用してRails 5.1.3を実行しています。

1. ActionController::RoutingError (No route matches [GET] "/cloudfoundryapplication") 
2. ActionController::RoutingError (No route matches [OPTION] "/cloudfoundryapplication") 

私は考え出し、外部アプリケーションピボタルの「/ cloudfoundryapplication」のそれのようにすべての詳細を見つけることができません：Railsの4からこのバージョンにアップグレードしているので、私は次のエラーがログに表示され見ていますCross-Origin Resource Sharing（CORS）に関連している可能性があります。私は問題を解決しようとするために 'rack-cors'宝石を使用しました。その結果、[OPTION]エラーは消えてしまいましたが、[GET]エラーは消えませんでした。ここで

は私のconfig/application.rbです：

Answer 1

私はピボタルサポートチームからの回答を得ました。

ピボットウェブサービスのAppsマネージャは、/ cloudfoundryapplicationエンドポイントをSpring Boot Actuatorインテグレーションのルートとして使用します。 AppsマネージャのSpring起動アクチュエータのエンドポイントを設定しているかどうかにかかわらず、AppsマネージャのUIでアプリケーションを表示すると、このエンドポイントが呼び出されます。

したがって、Spring Boot Actuatorエンドポイントを使用しないアプリケーションの場合、これらのエラーはAppsマネージャGUIを使用している間のみ表示されます。

そのようなSchrodingers冷蔵庫の光の猫：あなたが見ていなければ、エラーは表示されません。 CLIを介してログをチェックしたが、実際にはエラーは全くない。
