C# driver ver 2.21.0.0 MongoDB.Driver.MongoCommandException: Command aggregate failed - regression from driver 2.18.0

Hi,
I have that query:

IEnumerable<EFeatureType> featureTypeIds = enumerable values // EFeatureType is enumerable

var query = DbGeneralContext.FeatureTypes.AsQueryable(new AggregateOptions { AllowDiskUse = true })
                .Where(a => featureTypeIds.Contains(a.FeatureTypeId))
                .GroupJoin(DbGeneralContext.FeatureLicenses,
                    ft => ft.Id,
                    fl => fl.FeatureTypeId,
                    (ft, fl) => new { FT = ft, FL = fl })
                .SelectMany(a => a.FL,
                    (a, fl) =>
                        new
                        {
                            fl.AccountId,
                            fl.FeatureTypeId
                        })
                .GroupJoin(DbGeneralContext.Accounts,
                    f => f.AccountId,
                    acc => acc.Id,
                    (f, acc) => new { f, acc })
                .SelectMany(f => f.acc, (f, acc) => new
                {
                    accountId = acc.Id,
                    accountName = acc.Name
                })
                .Select(r =>
                    new RepAccountReferenceModelDal
                    {
                        AccountId = r.accountId,
                        AccountName = r.accountName
                    });
            try
            {
                List<RepAccountReferenceModelDal> res = await query.ToListAsync();
                
            }
            catch (Exception ex)
            {
                // hadle exception
            }
			
Explaine:
DbGeneralContext.FeatureTypes is IMongoCollection<FeatureTypeDal>
DbGeneralContext.FeatureLicenses is IMongoCollection<FeatureLicenseDal>
DbGeneralContext.Accounts is IMongoCollection<AccountDal>
FeatureTypeDal has a field: public EFeatureType FeatureTypeId { get; set; } // which is enum

under driver 2.18.0 the query runs well
under version 2.21.0.0 the following exception occur:
