Wrong use of cURL options

[tm-webentwicklung]

In \Model\AdminNotificationFeed.php you use this code in function parentGetFeedData():

$curl->setOptions( [ 'timeout' => 2, 'useragent' => $this->productMetadata->getName() . '/' . $this->productMetadata->getVersion() . ' (' . $this->productMetadata->getEdition() . ')', 'referer' => $this->urlBuilder->getUrl('*/*/*') ] );

In my installation of Magento it throws an error in \vendor\magento\framework\HTTP\Adapter\Curl.php, Line 71, because the options "timeout", "useragent" and "referer" are strings and not ints. You should use the Predefined Constants for cURL instead:

$curl->setOptions( [ CURLOPT_TIMEOUT => 2, CURLOPT_USERAGENT => $this->productMetadata->getName() . '/' . $this->productMetadata->getVersion() . ' (' . $this->productMetadata->getEdition() . ')', CURLOPT_REFERER => $this->urlBuilder->getUrl('*/*/*') ] );
