.NET: [Bug]: The parent parameters of the methods RetrieveIndexAsync and CreateCheckpointAsync in the ICheckpointStore interface are always null.

[helloxubo]

Description

When using the InProcessExecution.ResumeStreamAsync method to resume the workflow, the checkpoint lacks the 'parent' field.

Code Sample

csharp
 await using Checkpointed<StreamingRun> newCheckpointedRun =
     await InProcessExecution.ResumeStreamAsync(newWorkflow, savedCheckpoint!, checkpointManager);

 await foreach (WorkflowEvent evt in newCheckpointedRun.Run.WatchStreamAsync())
 {
     if (evt is ExecutorCompletedEvent executorCompletedEvt)
     {
         Console.WriteLine($"* Executor {executorCompletedEvt.ExecutorId} completed.");
     }

     if (evt is WorkflowOutputEvent workflowOutputEvt)
     {
         Console.WriteLine($"Workflow completed with result: {workflowOutputEvt.Data}");
     }
 }
