Eloquent Query Doesn't work

Hi, I'm modifying my like system a bit, everything works but the query to insert the notification about the like just put, doesn't work. I can't understand why!

This is my code:

function save_like(Request $request){
        
        $item = Items::findOrFail($request->item);
        
        if(Auth::user()->hasLiked($item)) {
            
            Auth::user()->unlike($item);
            return response()->json([
                'bool'=>false
            ]);

        } else {
            
            $like = Auth::user()->like($item);
            
            if($like == true){
                // notification
                Notifications::create([
                    'sender_id' => Auth::id(),
                    'recipient_id' => Request('recipient_id'),
                    'item_id' => Request('item'),
                    'notification_type' => "like",
                    'like_id' => Auth::user()->likes()->with('likeable')->first()->id,
                    'seen' => 2,
                ]);
                
            }
            
            return response()->json([
                'bool'=>true
            ]);
            
        }
    }
