The repository Get methods throw exception whenever a varchar field is NULLABLE and has NULL values. I have to replace them with empty strings all the time. Is this a problem with ZERO Repository framework ? Should it not handle NULL values.
"Operation Not allowed on NULL Values" is the error message I get on any Repository.Get(primary key) methods if it has NULL values.

This is not when Entity is not there for a primary key ( say Id for value 2.)
If the entity has varchar column that is NULLABLE and if NULL value exists in that column, It throws the following error.
"Operation Not allowed on NULL Values"
but the Entity record is present for the given primary key.
It looks like Abp is not checking NULL values before converting/casting to a String.
