Object size limits for source in ListView

I have added ListView component to my application, and following second example from here (

https://ej2.syncfusion.com/blazor/documentation/listview/customizing-templates/) have created new page, added the component and replaced the data source with data from my database. But as soon as I do that page loads, disconnects, reconnects to blazor engine and ends up displaying no content.
Empty




After more than 2 hours of troubleshooting I finally found out that there is a limit on size of the source.
My custom object has 17 columns, and one of them can fit large text. I found out that as soon as the data source list contains 31 objects where each has an attribute with text length of 366, that's where the controller fails.
Empty


To recreate, I have modified the example mentioned above to have the following code:

Empty


If I run it with 50 objects - everything works. When I run it with 55 - I get the described error.


Note that I'm not even displaying this attribute in the ListView component - it's only part of the object.
