Create a forum with Laravel 8 | Awards/Points to users: Award points to users | Part 84

I need your help I'm getting this error
call to member function addPoints on null

I did this in listener

$author = $event->reply->user->user_id;
$author->addPoints ($amount, $message);

Kindly asking if you can share a small guide on how to include image upload when creating a thread. It is possibly out of scope for this tutorial but I would appreciate the assistance, I wanted to create the logic similar to the one you used in the "jestream blog series" but the part I can't win, is where exactly I can add the image upload method in the CreateThread.php (job). Thank you in advance.

last request 🙏 can you add a share button for users to able to share the post to ( WhatsApp and twitter and copy link )

you have done alot thanks for this incredible tutorial
