No columns were selected" when there is no result returned by a query in when using QueryMultiple

I am using .net core 3.1 with dapper 2.0.35
I am getting error "No columns were selected" when using QueryMultiple

My code looks like following

public static List<List<dynamic>> GetEntityObjectFromClientId(string clientId, int? entityId)
        {
            List<List<dynamic>> lst = null;
            var _params = new DynamicParameters();
            _params.Add("@_client_id", clientId, DbType.String, direction: ParameterDirection.Input);
            _params.Add("@_entity_id", entityId, DbType.Int32, direction: ParameterDirection.Input);

            using (var db = new MySqlConnection(ConnectionString))
            {
                var resultSet = db.QueryMultiple(StoredProceduresName.mysqp, _params, commandType: CommandType.StoredProcedure);

                if (resultSet != null && HasRows(resultSet))//just added HasRows hack
                {
					var result1 = resultSet.Read();
                    if (result1 != null && result1.AsList().Count > 0)
                    {
                        lst = new List<List<dynamic>>();
                        lst.Add(result1.AsList());
                        lst.Add(resultSet.Read().AsList());
                        lst.Add(resultSet.Read().AsList());
                    }
                }
            }
            return lst;
        }

I have found a hack

   private static bool HasRows(SqlMapper.GridReader reader)//https://github.com/StackExchange/Dapper/issues/327
        {
            MySqlDataReader internalReader = (MySqlDataReader)typeof(SqlMapper.GridReader).
                GetField
                ("reader",
                System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance)
                .GetValue(reader);
            return internalReader.HasRows;
        }

Ideally HasRows method should be built into dapper
