Abp.EntityHistory.EntityHistoryHelperBase.IsAuditedPropertyInfo: Object reference not set ...

Hi community 😃 I’ve problem with auditing exception for PropertyInfo object. Abp version 6.4.0 .NetCore 5

Exeption Object reference not set to an instance of an object

I’ve readed in EFCore documentation /// <summary> /// Gets the <see cref="PropertyInfo" /> for the underlying CLR property that this /// object represents. This may be null for shadow properties or properties mapped directly to fields. /// </summary> PropertyInfo PropertyInfo { get; }

and that is a problem, because my entity looks this:

private string _gender; [NotMapped] [DisableAuditing] public GenderEnum Gender { get => GenderEnum.Parse(_gender); set => _gender = value?.Value; }

1. [DisableAuditing] not help
2. I use [NotMapped] attribute because propery is mapped to encapsulated filed and GenderEnum class is not a EF table object public class UserEntityTypeConfiguration : IEntityTypeConfiguration<User> { public void Configure(EntityTypeBuilder<User> builder) { builder.Property<string>("_gender").HasColumnName("Gender"); } } `
3. When i change my entity to public string Gender { get; set; } without explicitly encapsulation EntityHistoryHelper doesn’t throw any errors.

So i thing we have a problem with PropertyInfo = null
