AutoMapper DTO неправильно сериализуется для вставки производного класса ⇐ C#

[Anonymous]

У меня возникла проблема со вставкой производного типа оповещения в мое приложение. У меня есть базовый класс Alert и соответствующий ему DTO, а также производный класс OperationalAlert, который расширяет Alert, и OperationalAlertDto. Вставка распознается по AlertTypeId. Однако когда я пытаюсь вставить экземпляр OperationalAlert, значения возвращаются как нулевые. Я подтвердил, что все свойства правильно сопоставлены в моих конфигурациях AutoMapper, а необходимые поля как в DTO, так и в OperationalAlertDto заполнены. Несмотря на это, вставка по-прежнему не удалась. Кто-нибудь сталкивался с подобной проблемой или может дать рекомендации по ее решению?
public async Task CreateAlertAsync(AlertDTO alertDto)
{
if (alertDto == null)
{
throw new ArgumentNullException(nameof(alertDto), "Alert DTO cannot be null.");
}

Alert alert = alertDto.AlertTypeId switch
{
1 => _mapper.Map(alertDto) as Alert,
2 => _mapper.Map(alertDto) as Alert,
3 => _mapper.Map(alertDto) as Alert,
4 => _mapper.Map(alertDto) as Alert,
_ => throw new ArgumentOutOfRangeException(nameof(alertDto.AlertTypesId), "Invalid alert type"),
};

var addedAlertType = await _alertRepository.AddAsync(alert);
return addedAlertType;
}

Вот трассировка ошибки:
public class Alert
{
public int Id { get; set; }
public int AlertTypeId{ get; set; }
public int CreatorId { get; set; }
public string Name { get; set; }
public string Title { get; set; }

public int TemplateRefId { get; set; }
public int DepartmentId { get; set; }
public bool IsProcessChanged { get; set; }
public bool? IsPermanent { get; set; }
public virtual Department? Department { get; set; }
public virtual User? Creator { get; set; }
public virtual AlertType? Type { get; set; }
public virtual Template? Template { get; set; }
public int ChangeDetailId { get; set; }
public virtual ChangeDetail? ChangeDetail { get; set; }
public virtual ICollection? AlertRecipients { get; set; }
public virtual ICollection? AlertAttachments { get; set; }
public virtual ICollection? AlertUpdates { get; set; }
public virtual ICollection? LogEntries { get; set; }
public virtual ICollection? OperationDetails { get; set; }
}

using System.Collections.Generic;

namespace YourNamespace.Alerting.Domain.Model.Dto
{
public class AlertDTO
{
public int Id { get; set; }
public int AlertTypeId { get; set; }
public int CreatorId { get; set; }
public string UserName { get; set; }
public string Title { get; set; }
public string Content { get; set; }
public int TemplateRefId { get; set; }
public int DepartmentId { get; set; }
public bool IsProcessChanged { get; set; }
public bool? IsPermanent { get; set; }
public virtual ICollection? Recipients { get; set; }
public virtual ICollection? Updates { get; set; }
public virtual ICollection? Attachments { get; set; }
public virtual ICollection? Operations { get; set; }
public virtual ICollection? Logs { get; set; }
public int ChangeDetailId { get; set; }
}

public class ChangeDetailDto
{
public int Id { get; set; }
public string Name { get; set; }
}

public class RecipientDto
{
public int AlertId { get; set; }
public int RecipientId { get; set; }
}

public class UpdateDto
{
public int Id { get; set; }
public string Message { get; set; }
public int AlertId { get; set; }
public int TypeId { get; set; }
}
}

public class OperationalAlert : Alert
{
public AlertState State { get; set; }
public UrgencyLevel Urgency { get; set; }
public bool IsEnabled { get; set; }
public DateTime CreatedOn { get; set; }
public string Content { get; set; }
public DateTime ExpiresOn { get; set; }
public string Location { get; set; }
public string MessageContent { get; set; }
public string Description { get; set; }
public DateTime OccurrenceTime { get; set; }
public string Method { get; set; }
public string Reason { get; set; }
public virtual ICollection? Revisions { get; set; }
}

public enum AlertState
{
Active,
Inactive,
Expired,
Pending,
Resolved
}

public enum UrgencyLevel
{
Low,
Medium,
High,
Critical
}

Вот dto оповещения о продукте:
public class OperationalAlertDto : AlertDTO
{
public int Id { get; set; }
public string Title { get; set; }
public AlertState State { get; set; }
public UrgencyLevel Urgency { get; set; }
public bool IsEnabled { get; set; }
public string Content { get; set; }
public DateTime CreatedOn { get; set; }
public DateTime ExpiresOn { get; set; }
public string Description { get; set; }
public DateTime OccurrenceTime { get; set; }
public string Method { get; set; }
public string Reason { get; set; }
public string Location { get; set; }
public string MessageContent { get; set; }

public List? Revisions { get; set; }
}

public class OperationalAlertRevisionDto
{
public int RevisionId { get; set; }
public bool IsCurrent { get; set; }
public int AlertId { get; set; }
public int AlertTypeId { get; set; }
}

}

Вот мое определение дискриминатора:
builder.Services.AddControllers()
.AddNewtonsoftJson(options =>
{
options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
options.SerializerSettings.Converters.Add(
JsonSubtypesConverterBuilder
.Of(typeof(Alert), nameof(Alert.AlertTypeId I))
.RegisterSubtype(typeof(AlertInformational), 1)
.RegisterSubtype(typeof(AlertIncident), 2)
.RegisterSubtype(typeof(OperationalAlert), 4)
.SerializeDiscriminatorProperty()
.Build());
});
options.UseAllOfToExtendReferenceSchemas();
options.UseAllOfForInheritance();
options.UseOneOfForPolymorphism();
options.SelectDiscriminatorNameUsing(type =>
{
return type.Name switch
{
nameof(Alert) => "AlertTypeId",
_ => null
};
});

Вот трассировка ошибки, указывающая, что значения не могут быть вставлены как нулевые, что позволяет предположить, что сопоставление данных не распознается правильно, в результате чего значения не могут быть вставлены.Microsoft.EntityFrameworkCore.Update[10000]
