!Friendica Developers
I had an error in my Friendica instance where the API /api/statuses/friends_timeline was empty for weeks.
I traced it back to a bug in /src/Model/Post/Link.php. Apparently $curlResult can also be empty in line 129.
So

if (empty($curlResult) || !$curlResult->isSuccess()) {

should be the correct code in that line 129. Can $someone with github access please do the changes in the develop branch?
