meilisearch: The attribute does not work attributesToHighlight

Hello everyone! The word highlighting function in meilisearch does not work. Please help me solve this issue.

 public function __invoke (Request $request){
        
        $rubric  = Category::select('id', 'title')->where('type', 0)->get()->sortBy('title');
        $query = $request['query'];
        $post = Post::search($query,  function($meilisearch, $query, $options) use ($request){
            $date = strtotime(now());
            
            if(empty($request->rubric))
            {
                $options['filters'] = "status = 1";
            }
            else
            {
                $options['filters'] = "status = 1 AND (category_id = $request->rubric)";
                $options['attributesToHighlight'] = ['title', 'excerpt'];
            }
           
            return $meilisearch->search($query,$options );
        } )
        ->paginate(10);

        $modelCollection =  $post->load('category');
      
        return view('search.index', compact('post', 'request', 'rubric'));
    }
