Hello, what could be wrong if the repeater in the form.blade.php doesnt show in the admin panel? I used `@formField('repeater', ['type' => 'courseSections'])`, I checked if I use another, already existing/working repeater here, it displays, but not this one. I have setup the relationships.

I have a courseCategory module where I have some categories, and I want to display some courses in the courseCategory admin form (so, basically add courses to the categories as repeaters), so I made the courseSections module (this is the repeater module). I have setup belongsTo, belongsToMany and hasMany relationships, and also setup the repositories according to the documentation. But the courseSections repeater doesnt show on the admin form.

okay, it turns out that the repeater form was not created, after creating it, it works but cant save it, 
```
if (!isset($this->$slugAttribute)) {
                    throw new \Exception("You must define the field {$slugAttribute} in your model");
                }

                $slugParam = [
```
and I do have the $slugAttributes with a title inside of it.
