Problem with composer package on production server - Laravel project - php

Question

My problem is BadMethodCallException when trait method calls.
The package is kalnoy/nestedset for Laravel. On my local server all works perfect, but then I create my app on production server, I always have this exception:
Method Illuminate\Database\Query\Builder::descendants does not exist.
What I tried to do without result:
1. composer init
2. composer dump-autoload
3. delete and deployed project few times
4. composer require kalnoy/nestedset
5. Many hours of googling.
What thoughts about it? Has anyone had such a problem and sloved it?
My model:
namespace App;
use Illuminate\Database\Eloquent\Model,
Kalnoy\Nestedset\NodeTrait;
class Category extends Model
{
use NodeTrait;
protected $table = 'categories';
public function getOnMainItems($limit = 6)
{
return Category::where('main', 1)->limit($limit)->get();
}
}
Method what "doesn't exist":
namespace App\Services;
use App\Category;
use Kalnoy\Nestedset\Collection;
class CategoryService
{
/**
* #param string $slug
* #return array $categories
*/
public function getCatalogCategoriesForFilter(string $slug = '')
{
$categories = [];
if ($slug !== '') {
$currentCategory = Category::where([['category_slug', $slug], ['active', 1]])->limit(1)->get();
$categoriesByParent = Category::defaultOrder()->descendantsOf($currentCategory[0]->id);
foreach ($categoriesByParent as $category) {
$categories[] = $category->id;
}
}
return $categories;
}
}

Thanks everyone who helps me.
I sloved this.
The problem was in
Category::where('active', 1)->descendants($categoryId);
The Category::where('active', 1) returns queryBuilder object, which has not descendants method, it availabe on Category (model object).
The right way is
Category::descendants($categoryId);
I was embarrassed cause wrong way works on my local server. If somebody can explain this thing I would very grateful.
