Revisions list and get missing information - google-drive-api

Question

Using the Google APIs Explorer as well as the official C# library for Google Drive API v3, the response is missing most of the documented fields. I specifically need access to who did the revisions, which should be accessible via $.lastModifyingUser.
I've tried this on my domain admin account as well as a service account, so it shouldn't be a permission issue, at least not that I can see. What am I doing wrong, if anything?
List:
{
"kind": "drive#revisionList",
"revisions": [
{
"kind": "drive#revision",
"id": "1",
"mimeType": "application/vnd.google-apps.spreadsheet",
"modifiedTime": "2016-11-16T18:29:29.527Z"
},
{
"kind": "drive#revision",
"id": "14",
"mimeType": "application/vnd.google-apps.spreadsheet",
"modifiedTime": "2016-11-16T18:35:49.184Z"
},
...
Single get:
{
"kind": "drive#revision",
"id": "134088",
"mimeType": "application/vnd.google-apps.spreadsheet",
"modifiedTime": "2017-05-24T11:48:00.788Z"
}

Answer 1

You need to add fields="*", or fields="permissions(id,lastModifyingUser)" to your request to instruct Drive to return the full resource. By default, only a minimal set of properties is returned.

Answer 2

I was not able to retrieve the "lastModifyingUser" from the revisions API but I was able to retrieve the "lastModifyingUser" from the Files.get fro example:
File foundFile = service.files().get(id)
.setSupportsTeamDrives(true)
.setFields("parents, webViewLink, properties, lastModifyingUser")
.execute();
System.out.println("Found file is " + foundFile);
System.out.println("Parents " + foundFile.getParents());
System.out.println("Owners " + foundFile.getOwners());
System.out.println("Props " + foundFile.getProperties());
System.out.println("Last user " + foundFile.getLastModifyingUser());
