編集：JSONが不完全で、一部を切り取る必要がありました
サーバーから初めてクエリを実行すると、どういうわけか、1 つのエンティティに EntityState "Added" が設定されます。DBContextInitializer で 3 人のユーザーを作成します。これは、アプリを起動するたびに発生します。を呼び出すと「Unchanged」状態になりますがManager.rejectChanges()、これは手動で行う必要があります。
私がそれを行わず、別のエンティティ（おそらくチーム/注文/注文詳細）を保存すると、特定のユーザーは元のエンティティのコピーとして保存され、一意のキーが名前などの値と同じになります。何かを忘れている可能性があるため、コードを何十回もチェックしましたが、この User-Entity の状態の変更をどこにも呼び出していません。
これはManager.getChanges(EntityType の "User") の出力です:

ここからはあまり情報を引き出すことはできませんが、この特別な部分は奇妙だと思います。この配列の 3 番目のオブジェクトが、nullその配列の直後に State "Added" で表示されるのはなぜですか。
