cannot get custom filtering to work

[carolinecennis]

in ItemRepository I have a method:

    public function filterImages($query, $method, $clauseOperator, $value, $in)
    {
        if ($in) {
            call_user_func([$query, $method], 'product.categories', $value);
        } else {
            call_user_func([$query, $method], 'product.categories', $clauseOperator, $value);
        }
    }

when i filter for key "images" and value "image.jpg" this error always comes back:

"Argument 1 passed to Infrastructure\Database\Eloquent\Repository::filterImages() must be an instance of Optimus\Bruno\EloquentBuilderTrait, instance of Illuminate\Database\Eloquent\Builder given",

You have to import a proper Builder class by adding the following line near other "use" statements in your file:
use Illuminate\Database\Eloquent\Builder;
