Spreadsheets error " String could not be parsed as XML" - google-sheets-api

Question

When I try to get all titles of spreadsheets from Google drive, I got this message The string could not be parsed as XML:
ERROR -> SimpleXMLElement::__construct(): Entity: line 1: parser error : Start tag expected, '<' not found in C:\....
ERROR-> SimpleXMLElement::__construct(): { in C:\....
ERROR-> SimpleXMLElement::__construct(): ^ in C:\...
I try to connect on Gooogle drive, which I success, but I need to get the names of spreadsheets on Google drive, I previously use API v3 now I need to use V4.
this is code for call method getSpreadsheets();
$serviceRequest = new DefaultServiceRequest($token->access_token, $token->token_type);
ServiceRequestFactory::setInstance($serviceRequest);
$spreadsheetService = new Google\Spreadsheet\SpreadsheetService();
$spreadsheetFeed = $spreadsheetService->getSpreadsheets();
This is the code of method getSpreadsheets:
public function getSpreadsheets()
{
return new SpreadsheetFeed(
ServiceRequestFactory::getInstance()->get('v4/spreadsheets/1u7WYzJOYMX7uH3AIM70yVLOaHBy8p_uifuJe_Saa2T4?fields=sheets.properties.title')
);
}
And this is SpreadsheetFeed class, where is error causes:
namespace Google\Spreadsheet;
use ArrayIterator;
use SimpleXMLElement;
/**
* Spreadsheet feed.
*
* #package Google
* #subpackage Spreadsheet
* #author Asim Liaquat <asimlqt22#gmail.com>
*/
class SpreadsheetFeed extends ArrayIterator
{
/**
* The spreadsheet feed xml object
*
* #var \SimpleXMLElement
*/
protected $xml;
/**
* Initializes the the spreadsheet feed object
*
* #param string $xml the raw xml string of a spreadsheet feed
*/
public function __construct($xml)
{
$this->xml = new SimpleXMLElement($xml);
$spreadsheets = array();
foreach ($this->xml->entry as $entry) {
$spreadsheets[] = new Spreadsheet($entry);
}
parent::__construct($spreadsheets);
}
/**
* Gets a spreadhseet from the feed by its title. i.e. the name of
* the spreadsheet in google drive. This method will return only the
* first spreadsheet found with the specified title.
*
* #param string $title
*
* #return \Google\Spreadsheet\Spreadsheet|null
*/
public function getByTitle($title)
{
foreach($this->xml->entry as $entry) {
if($entry->title->__toString() == $title) {
return new Spreadsheet($entry);
}
}
return null;
}
}
I try to find a solution how to pass this error!
Any Help, how to solve this error?
Thanks!

This is solution for my app, migrate from v3 to v4 spreadsheets API:
$this->service_drive = new Google_Service_Drive($this->client);
$optParams = array('q'=> 'mimeType="application/vnd.google-apps.spreadsheet"');
$this->files = $this->service_drive->files->listFiles($optParams);
}
// $this->service_drive = new Google_Service_Drive($this->client);
//$optParams = array('q'=> 'mimeType="application/vnd.google-apps.spreadsheet"');
//$this->files = $this->service_drive->files->listFiles($optParams);
//$gdata_spreadsheets=$this->files;//my test
if($this->files !==null){
if (count($this->files->getFiles()) == 0) {
$gdata_spreadsheets=array("No Spreadsheets");
} else {
foreach ($this->files->getFiles() as $file) {
$gdata_spreadsheets[$file->getId()]=$file->getName();
}
}
}
//trenuto ispod code rjesavam
if($gdata->spreadsheet_id != '' && isset( $gdata_spreadsheets[$gdata->spreadsheet_id] ) && $this->files !== null){
$this->service = new Google_Service_Sheets($this->client);
$this->response = $this->service->spreadsheets->get($gdata->spreadsheet_id);
$this->sheets=$this->response->getSheets();
// $spreadsheet = $this->service_drive($gdata_spreadsheets[$gdata->spreadsheet_id]);
// $worksheetFeed = $spreadsheet->getWorksheets();
foreach ( $this->sheets as $sheet ){
$gdata_worksheets[$sheet->properties->sheetId]= $sheet->properties->title;
//$gdata_worksheets[]=$this->sheets;
}
//$gdata_worksheets[]=$gdata->worksheet_id;
if($gdata->worksheet_id != '' && isset( $gdata_worksheets[$gdata->worksheet_id] )){
$range = 'List 2!A1:Z';
$worksheet = $this->service->spreadsheets_values->get($gdata->spreadsheet_id, $range);
$cellFeed = $worksheet->getValues();
foreach( $cellFeed As $row) {
//$row = $cellEntry->getRow();
//$col = $cellEntry;
// $gdata_worksheets=$this->service;
if( $row > 1 ){
$gdata_columns=$row;
break;
}
}
}
}
} catch(Exception $e){
$error = $e->getMessage();
}
This is one part of my code, where is described how to migrate from v3 to v4 spreadsheets API.
