Google ads API PHP cannot run the documentation example

I'm running symfony 6 server / php 8.0.8, google ads api V22.0.0. Got dev token/refresh token, and all other infos, and annot run simple example from google and I'm not sure what I'm doing wrong. Here is my code:

use Google\Ads\GoogleAds\Lib\V14\GoogleAdsClientBuilder; use Google\Ads\GoogleAds\Lib\OAuth2TokenBuilder; use Google\Ads\GoogleAds\V14\Services\GoogleAdsServiceClient; use Google\Ads\GoogleAds\V14\Services\SearchGoogleAdsStreamRequest;     $developerToken = 'xxxx';       $clientId = 'yyyy';     $clientSecret = 'zzzz';     $refreshToken = 'dddd';      $loginCustomerId = 'vvvv';            try {         $oAuth2Credential = (new OAuth2TokenBuilder())             ->withClientId($clientId)             ->withClientSecret($clientSecret)             ->withRefreshToken($refreshToken)             ->build();         $googleAdsClient = (new GoogleAdsClientBuilder())             ->withDeveloperToken($developerToken)             ->withOAuth2Credential($oAuth2Credential)             ->withLoginCustomerId($loginCustomerId)             ->build();         $googleAdsServiceClient = $googleAdsClient->getGoogleAdsServiceClient();                  $query = 'SELECT campaign.id, campaign.name FROM campaign ORDER BY campaign.id';                  $stream2 = $googleAdsServiceClient->searchStream($loginCustomerId, $query         );                  foreach ($stream2->iterateAllElements() as $googleAdsRow) {            not reaching this        }     }      catch (\Google\ApiCore\ApiException $e) {         // Gérer les erreurs         $this->_logCall(self::LOG_GOOGLE_ADS, 'ERREUR:',$e->getBasicMessage());     }        

And here is the error:

Error 404 (Not Found)!!1

The requested URL /v14/customers/vvvv/googleAds:searchStream was not found on this server. That’s all we know.
