InvalidRequest moving DriveItem between Drives

Question

I am trying to move a DriveItem located in the root drive of a parent SharePoint site to a child sub-site.

Parent site: mydomain.sharepoint.com/sites/Graph - List: Documents

Child Site mydomain.sharepoint.com/sites/Graph/SubwebA - List: Documents

I am using the Microsoft Graph SDK v3.25.0:

var client = GetGraphClient();
var destDriveItem = new DriveItem
{
  ParentReference = new ItemReference
  {
    DriveId = destDriveID,
    Id = destDriveFolderID
  }
};

var response = await client
  .Drives[driveID]
  .Items[sourceDriveItemID]
  .Request()
  .UpdateAsync(destDriveItem);

All IDs are valid but UpdateAsync returns this error:

ServiceException: Code: invalidRequest
Message: Requested move requires an async response, add 'Prefer: respond-async' to allow
Inner error:

The same code works if I move the DriveItem between two Drives (Document Libraries) in the same site.

The issue is probably related to this GitHub issue (although that is for moving in the same site)

This is an unsupported action. From the documentation:

Items cannot be moved between Drives using this request.

Instead, you need to make two calls:

1. Copy the file to the new location
2. Delete the file from the old location

var client = GetGraphClient();

var parentReference = new ItemReference
{
  DriveId = destDriveID,
  Id = destDriveFolderID
};

var copyResponse = await client
  .Drives[driveID]
  .Items[sourceDriveItemID]
  .Copy(name, parentReference)
  .Request()
  .PostAsync();

var deleteResponse = await client
  .Drives[driveID]
  .Items[sourceDriveItemID]
  .Request()
  .DeleteAsync();
