Can you give the name of the model that uses the belongsToMany relation and to which model ?

class Variant extends Model
{
    public $table = 'as7_variant2_variant';

    public $belongsToMany = [
        'attribute' => [
           Attr::class,
           'table' => 'as7_variant2_attr_variant'
          ]
    ];
}

I think you want to have the Relation Controller two level deep which is currently not supported.

There is a tutorial on how to implement this here:
