本記事では、SXAサイトまたはSXAをベースにしたJSSサイトで、HTMLキャッシュが有効になっている場合にJSONデバイスを使用するとエラーが発生する、２つのシナリオについて説明します。
シナリオ１
SXAサイトがキャッシュを有効化したコンポーネントを持っている場合。
JSONデバイスを使用してフロントエンドでSXAサイトのページの再読み込みを実施すると、以下のエラーが発生する可能性があります：
Server Error in '/' Application. Rendering data contained rendering reference ID e1354fcc-4fe0-4b4c-aa11-78b793895dfa but that rendering ID was not present in the rendered renderings context. This ought not to occur. Description: An unhandled exception occurred.

シナリオ２
SXA PowerShellスクリプトで作成したJSSサイトがキャッシュを有効化したコンポーネントを持っている場合。
JSONデバイスを使用してフロントエンドでサイトの再読み込みを実施すると、以下のエラーが発生する可能性があります：
