            ->build();

        $this->client = (new GoogleAdsClientBuilder())->fromFile($this->account['certification_file'])
            ->withOAuth2Credential($oAuth2Credetial)
            ->withLogger(app('log'))
            ->build();
    } catch (InvalidArgumentException $th) {
        info(__METHOD__ . ',info:' . $th->getMessage());
    }
    return true;
}

protected function getAdsService()

    if ($this->client instanceof GoogleAdsClient) {
        return $this->client->getGoogleAdsServiceClient();
    }
    info(__METHOD__ . ' empty service, ' . $this->baseLogStr);
    throw new AdvertiseException("Empty google ads service", AdvertiseException::INIT_API_ERROR);
}

{
    $service = $this->getAdsService();
    $query = "query language... ";
    try {
        $iterator = $service->search($this->account['account_id'], $query, ['pageSize' => 2500]);
        foreach ($iterator->iterateAllElements() as $googleAdsRow) {
            // deal something ..., spended a little time(about 2 seconds).
        }
    } catch (ApiException $th) {

    }

Please decrease the number of your selected fields and date range and try again.
It's likely that your page token will be expired before you can get all data, if you're trying to fetch too much data.

For further questions regarding the API usage, in general, could you post in this forum instead?
Thanks.
