DashboardLayout error : Newtonsoft.Json.JsonSerializationException in browser console

[Ruan]

Hi,

I've tried to replicate this example here: https://www.syncfusion.com/downloads/support/directtrac/general/ze/BlazorApp132410259.zip , using the newest Blazor v17.4.39, to be able to add a panel dynamically, but I get multiple errors in the browser console like this:

ejs.interop.min.js:1 Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[Syncfusion.EJ2.Blazor.Layouts.DashboardLayoutPanel]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.

I have attached the source code, please run and look at browser console output after clicking on the Add Panel button. Even though the panel is dynamically added in the UI, you still get the unexpected errors in the browser console...plz assist since I want to use this object in an upcoming project?

Regards,

RC
