Chrome client crontab

[XhonorSkillline]

When using the functionality via cron, the file completes its work before receiving the result from ChromeClient (even with the wait functionality). What to do in this case? How can I make cron wait for the results from the browser to complete?

function example($url) {
        $client = Client::createChromeClient(null, null, [
            'port' => $availablePort,
        ]);

        $client->request('GET', $url);
        $client->waitForElementToContain('body', '{"status":"success"', 10);
        $data = $client->getCrawler()->filter('body')->text();

        $client->quit();

        return $data;
}

Cron function:

foreach($lala as $url) {
        $data[] = example($url);
}

print_r($data); // empty result instantly without waiting
