Gateway Timeout on Group Drive

Question

I do a simple get on https://graph.microsoft.com/v1.0/groups/ee7ca7f8-f838-4caf-ab9b-84c133ccd003/drive for a new group and then I get a 504 Gateway Timeout with this body:

{
  "error": {
    "code": "UnknownError",
    "message": "",
    "innerError": {
      "request-id": "f3edd69f-6747-49fb-b41c-925ef2381bad",
      "date": "2017-07-28T20:12:58"
    }
  }
}

Why?

Answer 1

Until a drive is opened via the UI it isn't fully provisioned.
