makeAdmin method
Makes a user a super administrator.
request - The metadata request object.
Request parameters:
userKey - Identifies the user in the API request. The value can be the
user's primary email address, alias email address, or unique user ID.
$fields - Selector specifying which fields to include in a partial
response.

this method will complete with the same error.
Implementation
async.Future<void> makeAdmin(
  UserMakeAdmin request,
  core.String userKey, {
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'admin/directory/v1/users/' +
      commons.escapeVariable('$userKey') +
      '/makeAdmin';
  await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
