I am using the Drive REST API to download a file. I am making a GET request using the file id and I get a `file not found exception`.

```
{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "notFound",
    "message": "File not found: xxxxx",
    "locationType": "other",
    "location": "file"
   }
  ],
  "code": 404,
  "message": "File not found: xxxxx"
 }
} 

```

I have also generated the apikey and I am using it in my GET request.The file does exist so I am unsure what I am missing here.
