Call to a member function links() on array

Question

I´m using Laravel 8 with Livewire.

I have create this to show a list of items and the user can apply filters as well. Upon load the data gets shown, 10 records per page. However when I try to click next page or a specific page number I get the error "Call to a member function links() on array..."

I´m also using repository and it´s injected on the livewire component.

use App\Models\Repositories\Interfaces\LojaAdesaoRepositoryInterface;
use Livewire\Component;
use Livewire\WithPagination;

This is my component

class Adesao extends Component
{
    use WithPagination;

    protected $repository;    
    public $cnpj;
    public $razaoSocial;
    public $nomeFantasia;
    public $regulamentacaoId;
    public $regiaoId;
    public $faturamentoId;
    private $filtros = [
        "cnpj" => "",
        "razao_social" => "",
        "nome_fantasia" =>  "",
        //"regulamentacao_id" =>  "",
        //"regiao_id" =>  "",
        //"faturamento_id" =>  ""
    ];

    private $lojas = [];
    
    protected $listeners = ['regiaoMudanca' => 'regiaoMudanca', 'faturamentoListener' => 'faturamentoListener', 'regulamentacaoListener' => 'regulamentacaoListener'];

    public function mount(LojaAdesaoRepositoryInterface $respository)
    {
        
        $this->repository = $respository;
        $lojas = $this->retornaListaInicial();
        $this->setLojas($lojas);
    }

    public function render(LojaAdesaoRepositoryInterface $respository)
    {   
        $this->repository = $respository;
        $lojas = $this->getLojas();
        
        return view('livewire.lojas.adesao',['lojasAdesao' => $lojas]);
    }

    public function regiaoMudanca($value){
        $this->filtros['regiao_id'] = $value;
    }

    public function faturamentoListener($value){
        $this->filtros['faturamento_id'] = $value;
    }

    public function regulamentacaoListener($value){
        
        $this->filtros['regulamentacao_id'] = $value;
    }

    public function submitForm(LojaAdesaoRepositoryInterface $respository){
        
        $this->resetPage();
        $this->repository = $respository;
        $this->filtros["cnpj"] = $this->cnpj;
        $this->filtros["razao_social"] = $this->razaoSocial;
        $this->filtros["nome_fantasia"] =  $this->nomeFantasia;
        
        $lojas = $this->repository->filterBy($this->filtros);
        $this->setLojas($lojas);
        
    }

    private function retornaListaInicial(){
        return $this->repository->filterBy([]);
    }

    private function setLojas($lojas){
        //dd($lojas->links());
        $this->lojas = $lojas;
    }

    private function getLojas(){
        return $this->lojas;
    }
}

Short answer

move this from mount to render method:

$lojas = $this->retornaListaInicial();
$this->setLojas($lojas);

Explanation

Notice your both methods mount and render, while mount is called once on component startup, render is called every server call. So somehow when you change the page, only render is called and $lojas = $this->getLojas(); returns its initial value, a empty array.

    public function mount(LojaAdesaoRepositoryInterface $respository)
    {
        
        $this->repository = $respository;
        $lojas = $this->retornaListaInicial();
        $this->setLojas($lojas);
    }

    public function render(LojaAdesaoRepositoryInterface $respository)
    {   
        $this->repository = $respository;
        $lojas = $this->getLojas();
        
        return view('livewire.lojas.adesao',['lojasAdesao' => $lojas]);
    }
