為什么會出現?我這邊的操作是拖拽修改順序

實現代碼：

public async Task MoveOrganizationUnit(MoveNodeInput<long> input)
        {
            var source = await _organizationUnitRepository.GetAsync(input.SourceId);
            var query = _organizationUnitRepository.GetAll();
            await Task.Run(() =>
            {
                _organizationUnitRepository.MoveNode<ExtendedOrganizationUnit, long, long?>(input.SourceId, input.TargetId, input.DropPosition, query);
            });
        }

MoveNode方法：

public static TEntity MoveNode<TEntity, TPrimaryKey, TParentKey>(this IRepository<TEntity, TPrimaryKey> repository, TPrimaryKey sourceNodeId, TParentKey targetNodeId, NodeMoveType moveType, IQueryable<TEntity> query = null)
            where TEntity : class, ISimpleTreeEntity<TEntity, TPrimaryKey, TParentKey>, IEntity<TPrimaryKey>
        {
            repository.ResetNodes<TEntity, TPrimaryKey, TParentKey>(null, query);
            var sourceNode = repository.Get(sourceNodeId);
            var targetNode = targetNodeId == null ? null : repository.Get((TPrimaryKey)(object)targetNodeId);
            return repository.MoveNode<TEntity, TPrimaryKey, TParentKey>(sourceNode, targetNode, moveType, query);
        }

該問題待解決中。。。。。。
