My solution uses multi tenant However, I have an entity that is only created for the host tenant After upgrading from 7.3.2 to 7.4.0-rc.4, that entity's GET api generates an error
An exception occurred while iterating over the results of a query for context type '"MySite.EntityFrameworkCore.MySiteDbContext"'."
""System.InvalidCastException: Unable to cast object of type 'System.DBNull' to type 'System.String'.

Hello linhhn@arius.vn ,
Can you please share more steps to reproduce this issue, and also it will be helpful if you share some details of the entity that you are getting error. Like Entity parameters, and its inheritance.
Thank you, Anjali

My solosution is Separate tenant schema Before upgrading to version 7.4.0-rc.4, I had an entity that was not checked into Multi-tenant. It works fine in 7.3.2. After upgrading, if you call the Get all data api of that entity, a 500 error will occur All code related to this entity is automatically generated, I do not customize
