NullReferenceException when using OwnsOne

[Ben555555]

I'm getting the following exception when calling dbContext.BulkSaveChanges():

System.NullReferenceException: Object reference not set to an instance of an object.
at EFCore.BulkExtensions.DbContextBulkTransactionSaveChanges.<>c.b__2_3(IEntityType e)
at EFCore.BulkExtensions.DbContextBulkTransactionSaveChanges.<>c__DisplayClass2_0.b__6(<>f__AnonymousType14 g) at Medallion.Collections.TopologicalSorter.TopologicalSort[TElement](ITopologicalSortProvider1 provider)+MoveNext()
at System.Collections.Generic.List1.AddRange(IEnumerable1 collection)
at System.Linq.Enumerable.ConcatIterator1.ToList() at EFCore.BulkExtensions.DbContextBulkTransactionSaveChanges.SaveChangesAsync(DbContext context, BulkConfig bulkConfig, Action1 progress, Boolean isAsync, CancellationToken cancellationToken)
at EFCore.BulkExtensions.DbContextBulkTransactionSaveChanges.SaveChangesAsync(DbContext context, BulkConfig bulkConfig, Action1 progress, CancellationToken cancellationToken) at EFCore.BulkExtensions.DbContextBulkTransaction.ExecuteAsync[T](DbContext context, Type type, IEnumerable1 entities, OperationType operationType, BulkConfig bulkConfig, Action`1 progress, CancellationToken cancellationToken)

I looks like e is null here

Func<IEntityType, IEnumerable<IEntityType>> getFks = delegate(IEntityType e)
{
	IEntityType e2 = e;
	return from x in e2.GetForeignKeys()
		where x.PrincipalEntityType != e2
		select x.PrincipalEntityType;
};

coming from

var first = TopologicalSortExtensions.OrderTopologicallyBy(enumerable, g => getFks(g.EntityType).SelectMany((IEntityType x) => addedLookup[x]), null);

When analyzing g I see that the contains the following information:

{ State = Added, Entities = System.Collections.Generic.List`1[System.Object], EntryType = AddressEntity, EntityType = }}

AddressEntity is an OwnsOne Relation type, so I guess that's the reason that there is no entity type?

I'm using version 8.0.1 and SQL Server.
