Changing the ScraperService.php of this part:

$qb = Insert::intoTable('scraper_data');
$qb->setValue('url', $qb->param($url, ELGG_VALUE_STRING))
->setValue('hash', $qb->param(sha1($url), ELGG_VALUE_STRING))
->setValue('data', $qb->param(serialize($data)));

$result = $this->db->insertData($qb);

$dbprefix = elgg_get_config('dbprefix');
$query = "
INSERT INTO {$dbprefix}scraper_data
SET url = :url,
    hash = :hash,
    data = :data
ON DUPLICATE KEY UPDATE
    data = :data
";

$result = $this->db->insertData($query, [
   ':url' => (string) $url,
   ':data' => serialize($data),
   ':hash' => sha1($url),
]);

Made me happy to, thanks a lot :-)
