私のワークフローでは、マーケティング リストから連絡先を挿入または削除します。入力ブール値パラメーター値に従います。True-> 挿入 -> 連絡先が存在する場合 THEN return -> そうでなければ False -> 削除 -> 存在しない場合 THEN return
この WFA はインシデントで実行されます。
最初に起動すると、うまく機能し、連絡先を削除または追加します。しかし、ブール値を変更して再実行すると、次の例外メッセージが表示されます。
エラーが原因でワークフローが一時停止しました: 未処理の例外: System.NullReferenceException: オブジェクト参照がオブジェクトのインスタンスに設定されていません。ContactToMList.ContactToMList.Execute (CodeActivityContext executionContext) で System.Activities.CodeActivity.InternalExecute (ActivityInstance インスタンス、ActivityExecutor エグゼキューター、BookmarkManager ブックマーク マネージャー) で System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody (ActivityExecutor)

コンテキストを取らないようです。
