Hi @Fady1956,

We need additional details in order to fully understand what the problem is:

  1. What code did you generate?
  2. What kind of application do you have? WebAssembly, Auto, Server?
  3. Which version of .NET is the app using?
  4. Does this exception occur in all generated pages or just one?
  5. What is the latest .NET framework version you have installed on your machine? This can be determined by running dotnet --version or dotnet --info.

Hi Korsev,

  1. the code I generated is for CRUD
  2. the application is Server
  3. Microsoft.EntityFrameworkCore 9.0.2
  4. this exception occurs in all grid pages so far.
  5. dotnet version 9.0.200

I regenerated the code after the new version 6.0.6 and it seems fixed.
I will test it further later on.
