Hi, We're using the lazychaser/laravel-nestedset (on gidhub) / Kalnoy\Nestedset (composer/packagist) package. The seeder is working. But when i want to get the tree by a function in my model, it gives errors that are untraceable for me:

(deleted parts not needed for problem solving)

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Kalnoy\Nestedset\NodeTrait;


/**
 * Class Category
 */
class Category extends Model
{
    use \Dimsav\Translatable\Translatable;
    use NodeTrait;

    protected   $fillable = [
        'visible'
    ];

    /**
     * Get the product records associated with the category.
     */
    public function products()
    {
        return $this->hasMany('App\Product');
    }
   
    /**
     * Get the category feature records associated with the category.
     */
    public function categoryFeatures()
    {
        return $this->hasMany('App\CategoryFeature'); // this one is working right!
    }

    /**
     * Get the category feature records associated with the category.
     */
    public function allCategoryFeatures()
    {
        // when visiting the url where i'm 3 levels deep, i'm getting the right category, but as you see:
        print_r($this->isRoot());  // returns: 1       
        print_r($this->ancestors()->get()->toTree()); // returns: Kalnoy\Nestedset\Collection Object ( [items:protected] => Array ( ) )
        // it doesn't seem to recognise the nestedset system

        $ancestors         = ($this->isRoot()) ? NULL : $this->ancestors()->get();

        $categoryCollection   = (empty($ancestors)) ? $this->with('categoryFeatures') : $ancestors->toTree()->with('categoryFeatures');

        return $categoryCollection;
    }
///////////
// etc
//////////
}

As you can see in the comments in the code it doesn't seem to get the nestedset system...

In the end i'm getting:

BadMethodCallException in Builder.php line 2437:
Call to undefined method Illuminate\Database\Query\Builder::addEagerConstraints()
1. in Builder.php line 2437

etc

can't $this be accessed in the model or something? do you have any ideas on how to get this working?
