Expected or Desired Behavior

When copying a file and omitting "name", original file name is used, as specified in the documentation.

Observed Behavior

Copy operation is Accepted (202), but monitor endpoint reports:

{
  "@odata.context": "https://{domain}-my.sharepoint.com/personal/{username}/_api/v2.1/$metadata#drives('default')/operations/$entity",
  "id": "{operationId}",
  "status": "failed",
  "error": {
    "code": "generalException",
    "message": "General exception while processing"
  }
}

Steps to Reproduce

I could not find a way to get the copy to work without providing "name", so the steps are just:

POST https://graph.microsoft.com/v1.0/users/{username}/drive/items/{itemId}/copy

{
  "parentReference": {
    "driveId": "{driveId}",
    "id": "{parentItemId}"
  }
}

^ This fails.

POST https://graph.microsoft.com/v1.0/users/{username}/drive/items/{itemId}/copy

{
  "parentReference": {
    "driveId": "{driveId}",
    "id": "{parentItemId}"
  },
  "name": "foo"
}

^ This works with the same IDs, just "name" added.
