Error when using NestableTrait

[josegus]

Summary of problem or feature request

I recently installed https://github.com/atayahmet/laravel-nestable and added NestableTrait to my model "Categoria". This is causing an issue, returning "No available engine for App\Categoria" message. I really need to use both (datatables and nestable). Any idea how can i make both work correctly?

I have not run "vendor publish" for datatables, since I don't need customization. I have other models (Producto, Cliente) working the same: ajax and using datatables() helper, but without NestableTrait.

Code snippet of problem

I'm using ajax, so my code looks like:

    // Ajax method
    public function list(Request $request)
    {
        $query = Categoria::select(['id', 'nombre']);

        return datatables($query)->toJson();
    }

And my Categoria model:

class Categoria extends Model
{
    use NestableTrait;

    protected $table = 'categoria';

    protected $fillable = ['nombre', 'slug', 'icono', 'descripcion', 'categoria_id'];

    protected $hidden = ['created_at', 'updated_at'];
}

System details

• Operating System: Ubuntu 16.04
• PHP Version: 7.2
• Laravel Version: 5.7
• Laravel-Datatables Version: 8.0

Self joins is not yet supported by the package. There is a PR that address this but it breaks on the soft deletes model and was reverted https://github.com/yajra/laravel-datatables/pull/2051.
