Missing details in Error Payload

まず、ClientV3Exception と cf-java-client における Error ペイロードの処理を追跡します。この issue にある JSON レスポンスと test_mode_info の例を参照してください。サーバー側のコンテキストは errors_controller.rb にあり、問題は manifest.yml のパースに関するものです。Error オブジェクトが、cloud controller のログを必要とせずに test_mode_info の追加詳細を公開すれば完了です。

When an ClientV3Exception is thrown there is more details available in the message than exposed through the Error object. Specifically it would be useful to get the content test_mode_info which had additional details which in this case was bad YAML provided in the manifest.yml. The only way to get these details currently is to search through the cloud controller logs but I assume they come back in the JSON payload that the cf java client could sift through and provide on the Error class.
