Laravel repository pattern - error with relations

I am beginner in Laravel and php. I have in my project Laravel 5.8 I make Repositories paternities in my project. I write Repository Base, Interface and controller.

I have this code:

1. BaseRepository:

   abstract class BaseRepository implements RepositoryInterface {

   protected $model;
   
   public function getAll(string $order = 'id', string $by = 'desc')
   {
       return $this->model->orderBy($order, $by)->get()->appends(request()->query());
   }
   
   public function getAllWithPaginate(string $order = 'id', string $by = 'desc', int $perPage = 1)
   {
       return $this->model->orderBy($order, $by)->paginate($perPage)->appends(request()->query());
   }
   
   public function with($relations)
   {
       return $this->model->with($relations);
   }
   
   public function create(array $data)
   {
       return $this->model->create($data);
   }
   
   public function save(array $data): int
   {
       $model = $this->model->create($data);
       return $model->id;
   }
   
   public function update(array $data, int $id)
   {
       return $this->model->where("id", "=", $id)->update($data);
   }
   
   public function delete(int $id)
   {
       return $this->model->destroy($id);
   }
   
   public function find(int $id, string $order, string $by)
   {
       return $this->model->find($id)->orderBy($order, $by);
   }
   
   public function findOrFail(int $id, string $order, string $by)
   {
       return $this->model->findOrFail($id)->orderBy($order, $by);
   }
   
   public function getModel()
   {
       return $this->model;
   }
   

   }

2. RepositoryInterface:

   interface RepositoryInterface { public function getAll(string $order, string $by);

   public function getAllWithPaginate(string $order, string $by, int $perPage);
   
   public function create(array $data);
   
   public function save(array $data);
   
   public function update(array $data, int $id);
   
   public function delete(int $id);
   
   public function find(int $id, string $order, string $by);
   
   public function findOrFail(int $id, string $order, string $by);
   
   public function getModel();
   

   }

3 AdRepository:

class AdRepository extends BaseRepository
{

    public function __construct(Ad $model)
    {
        $this->model = $model;
    }

    public function search(string $query, string $order = 'id', string $by = 'desc', int $perPage = 1)
    {
        return $this->model->where('title', 'LIKE', '%' . $query . '%')->orWhere('id', 'LIKE', '%' . $query . '%')->orWhere('content', 'LIKE', '%' . $query . '%')->orderBy($order, $by)->paginate($perPage)->appends(request()->query());
    }
}

4. Controller:

   public function index(Request $request) { if($request->input('query') != ""){ $adsList = $this->repository->with('author')->search($request->input('query')); } else{ $adsList = $this->repository->with('author')->getAllWithPaginate(); }

       return view('modules.ad.ad_list', ['adsList' => $adsList]);
   }
   

When I run my code I have error: Call to undefined method Illuminate\Database\Eloquent\Builder::getAllWithPaginate()

How can I fix it?

Please help me.
