По сути, то, что говорит заголовок, по какой-либо причине, когда я вызываю clientContext.ExecuteQuery();
и, например, в списке, в который входят данные, отсутствует столбец, я не получаю исключения, он на самом деле просто работает, как ожидалось, и у меня на go и выясните, что могло стать причиной отсутствия данных.
Я использую пакет NuGet Microsoft.SharePoint2016.CSOM версия 16.0.4690.1000
Приветствуются любые намеки или предложения, указывающие мне в правильном направлении. Вполне возможно, что я здесь немного тупой.
Вот полный блок кода, который я использую для обновления элементов списка:
public override object UpdateEntity(object entity)
{
if (entity == null)
{
// if the definition is null throw argument null exception.
throw new ArgumentNullException(nameof(SharePointDefinition));
}
// check for incorrect type being passed in that we can still handle
if (entity is List<SharePointDefinition> definitions)
{
return UpdateEntities(definitions);
}

ExceptionHandlingScope exceptionScopeSubmit = new ExceptionHandlingScope(clientContext);
// run single definition submit to SP.
