I am trying to use the DataGrid and I'm getting an error on binding.  The error is:

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
Unhandled exception rendering component: Unable to set property 'DataSource' on object of type 'IgniteUI.Blazor.Controls.DataGrid'. The error was: Blazor.platform.readInt64Field is not a function

The grid is a very simple grid defined: 

<DataGrid Width="100%" Height="100%" AutoGenerateColumns="false" DataSource="HmpContractors"> <NumericColumn Field="Id" IsHidden="true" /> <TextColumn Field="Name" HeaderText="Name" /> </DataGrid>

Here is a sample of the JSON data it is trying to bind to:
