I'm finding the same issue, and it has nothing to do with backing off or waiting... The API explorer works perfectly, but a URL in the next tab, developed from the explorer, fails every time. Not often... always!

The issue seems to be related to the query being more complex than a single item. e.g. if I ask for name= or something in parent then it works. If I combine both with "and" then it fails.

For example:

https://www.googleapis.com/drive/v3/files?q=%270B0ap0WDOII5mbjdwajNBMlRoZUU%27+in+parents&key={my key}

works fine, but

https://www.googleapis.com/drive/v3/files?q=%270B0ap0WDOII5mbjdwajNBMlRoZUU%27+in+parents+and+name%3D%27test.TXT%27&key={my key}

fails with

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "internalError",
    "message": "Internal Error"
   }
  ],
  "code": 500,
  "message": "Internal Error"
 }
}

Note that both of those URLs are copied directly from the "API's Explorer" section of https://developers.google.com/drive/v3/reference/files/list with my API key added to the end of each.

It also fails in exactly the same way with the v2 interface.

Could there be a bug in the API? Having to do with files in a public folder?

Answer 2

G recommends that your app should backoff and retry 500 errors. Did you try this and does it persistently fail on the retry?

It's a known issue with drive.file scope, use drive.readonly.metadata additionally for queries.

Edit: It looks like the query is also broken with drive.appdata scope. I'm making sure that we're fixing it as soon as possible.
