Google-api-php-client: Undefined property: Google_Service_Drive::$parents

[coollorenzo]

I'm using the code example from the gdrive docs:
`/**

• Print a file's parents.
  *
• @param Google_Service_Drive $service Drive API service instance.
• @param String $fileId ID of the file to print parents for.
  */
  function printParents($service, $fileId) {
  try {
  $parents = $service->parents->listParents($fileId);

foreach ($parents->getItems() as $parent) {
  print 'File Id: ' . $parent->getId();
}

} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
}`

But I get the error Undefined property: Google_Service_Drive::$parents and I also couldn't find any code referencing parents so is the option to get and list parents removed?

Right now this client library only supports v3 of the Drive API. You will want to use files.get with ?fields=parents to list parents: https://developers.google.com/drive/api/v3/migration
