文件夹的 Shortcut 无法使用

[RockerFlower]

文件的 Shortcut 可以访问，文件夹的似乎被当作文件了

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "fileNotDownloadable",
    "message": "Only files with binary content can be downloaded. Use Export with Google Docs files.",
    "locationType": "parameter",
    "location": "alt"
   }
  ],
  "code": 403,
  "message": "Only files with binary content can be downloaded. Use Export with Google Docs files."
 }
}
