Hana xsodata cannot check null value in nvarchar filed

Hi experts,

I have an nvarchar field with nullable is false of my hana table.

While this nvarchar value with null (eg. <field></field>) is inserted into the table through the xsodata,

it can be able inserted to the table. I think I will get an exception by inserting null value to the not null field

thrown by the xsodata. Please let us know why xsodata cannot check null or not for nvarchar field?

Best regards,

Nyein.
