Issue #1:- While defining columns with Exception throws like on button click-- System.InvalidOperationException: The converter specified on 'Syncfusion.Blazor.TreeGrid.TreeGridColumn.EditTemplate' does not derive from JsonConverter or have a public parameterless constructor.
<SfTreeGrid @ref="TreeGrid" DataSource="@TreeGridRows"
IdMapping="Id"
ParentIdMapping="ParentId"
TreeColumnIndex="0" AllowSorting="true" AllowPaging="true" Columns="@TreeColumns">
</SfTreeGrid>

Issue2:-To overcome this customer defined the columns using
<SfTreeGrid @ref="TreeGrid" DataSource="@TreeGridRows"
IdMapping="Id"
ParentIdMapping="ParentId"
TreeColumnIndex="0" AllowSorting="true" AllowPaging="true">
<TreeGridColumns>
@foreach (var treeGridColumn in @TreeColumns)

{ <TreeGridColumn Field="@treeGridColumn.Field" HeaderText="@treeGridColumn.HeaderText" Width="@treeGridColumn.Width"></TreeGridColumn> }

</TreeGridColumns>
</SfTreeGrid>
