Symfony のバージョン2.0.17を実行しているサイトがあります(はい、それが廃止されていることはわかっています。2.2.x への移行が進行中です)。次のメッセージでエラー 500が発生し始めた数日前までは問題なく動作していました。
警告: DOMDocument::schemaValidate(): /var/www/customers/customername/symfony/vendor/symfony/src/Symfony/Component/Validator/Mapping/Loader/XmlFileLoader.php 行 197 のスキーマが無効です
で編集フォームを作成しようとすると、エラーが発生しますFormBuilder。私たちの開発環境とテスト環境ではすべてが正常に機能するため、トラブルシューティングが非常に困難です。
この問題の考えられる原因は何ですか? 1 月以降、サイトへの新しい変更はプッシュされておらず、3 月の初めに公開された最新のコンテンツのタイムスタンプであるため、3 月の初めには確実に機能していました。
完全なスタック トレースの関連部分を次に示します。DOMDocument->schemaValidate()警告の原因となるメソッドです。
