I am running into an odd error with the Radzen Gantt Chart where when I dispose my component or make an edit to a task in the gantt chart, when the rendering reoccurs to account for the modification, the blazor.server.js throws an "Object Not Referenced" error.
I am running .Net 6 with Radzen.Blazor version 4.31.4
Below is the declaration for my gantt chart..
<TelerikGantt @ref="@gantt" Data="@job.JobTasks.Where(r => r.Billable).OrderBy(r => r.SortOrder)" @bind-View="@SelectedView" ColumnResizable="true" TreeListWidth="50%"

PercentCompleteField="ToDatePercentComplete">

I have debugged my list and I have validated that the IdField, ParentIdField, and PercentCompleteField are all populated and not null.. Not sure what else could be throwing this error..
Appreciate any help and guidance!!
