Exception prevents page from building in UI

Radzen Blazor Studio
1

I have a project that I have been working on in the IDE for some time. I moved it over to Blazor Studio and it loaded up as expected except for one page...

The page fails to load its UI due to an exception that does not seems to occur in the IDE. I analyzed the project and this was the output:

      > System.ArgumentNullException: Value cannot be null. (Parameter 'input')

I cannot find any errors in my code. Is this a bug

@korchev Looking at you haha, since your name shows up multiple times in the Radzen references.

If you have Radzen Blazor Studio subscription you can send us your application to info@radzen.com to check it locally.
