I think there is error in your simple method. You must take care about your table name and column name, and type of column which you fetched from DB in simple function. In case if you are not sure that row have values for all columns or not you should use Option so may be there you catch this error due to unavailability of data.

You should ensure in simple function about get[DATA TYPE] or get[Option[DATA TYPE]]
