при выборе запроса 

select * from Permissions where AppId='yZVwUoxKQCu'  FOR JSON PATH,INCLUDE_NULL_VALUES

выполняется на сервере sql, он возвращает полные данные с оберткой массива без неожиданного завершения. Когда запрос читается с помощью DataReader в C #, тот же результат запроса неожиданно завершается. SQL выполнить, используя метод ниже.

Запрос как этот 

var sql = $"select * from Permissions where AppId='{AppId}'  FOR JSON PATH,INCLUDE_NULL_VALUES";
            var res = Connection.ExecuteScalarCommand(sql);

 public static String ExecuteScalarCommand(string sql)
        {
            string CS = DbConnectionString;
            SqlConnection con = new SqlConnection(CS);
            string val = "";
            try
            {

                con.Open();
                SqlCommand cmd = new SqlCommand(sql, con);
                val = cmd.ExecuteScalar().ToString();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message.ToString());
            }
            finally
            {
                con.Close();
            }
            return val;

        }

Выходные данные, предоставленные сервером sql direct, соответствуют ожидаемым выходным данным.

но из ядра asp.net выведено

ExecuteScalar имеет ограничение на число символов:

Первый столбец первой строки в наборе результатов или нулевая ссылка (Ничего в Visual Basic), если результатнабор пуст.Возвращает максимум 2033 символа.

Для преодоления этого вам потребуется использовать другую функцию, например ExecuteReader .
