I am trying to move a DriveItem located in the root Web of an M365 site to a sub-web of the same site -
Source Web: mydomain.sharepoint.com/sites/Graph - List: Documents
Destination Web: mydomain.sharepoint.com/sites/Graph/SubwebA - List: Documents
The code doing the move with the Graph API 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. When UpdateAsync is finished, I get 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 Web): https://github.com/microsoftgraph/microsoft-graph-docs/issues/2890
