ErrorException in Laravel

I created a Laravel project and in this project, I created a controller called PhotoController.php. In this file, the code is this:

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;

class PhotoController extends Controller {
  //Display a listing of the resource.
  //@return \Illuminate\Http\Response
  public function index(){
    return 'index';
  }

  //Show the form for creating a new resource.
  //@return \Illuminate\Http\Response
  public function create(){
    return 'create';
  }

  //Store a newly created resource in storage.
  //@param \Illuminate\Http\Request $request
  //@return \Illuminate\Http\Response
  public function store(Request $request){
    return 'store, uri: '. $request->path();
  }

  //Display the specified resource.
  //@param int $id
  //@return \Illuminate\Http\Response
  public function show($id){
    return 'show, id: '. $id;
  }

  //Show the form for editing the specified resource.
  //@param int $id
  //@return \Illuminate\Http\Response
  public function edit($id){
    return 'edit, id: '. $id;
  }

  //Update the specified resource in storage.
  //@param \Illuminate\Http\Request  $request
  //@param int $id
  //@return \Illuminate\Http\Response
  public function update(Request $request, $id){
    return 'update, uri: '. $request->path() .' - id: '. $id;
  }

  //Remove the specified resource from storage.
  //@param int $id
  //@return \Illuminate\Http\Response
  public function destroy($id){
    return 'destroy, id: '. $id;
  }
}

For this controller I created this route in web.php:

Route::resource('photo',[PhotoController::class]);

When I start server with command: php artisan serve, an error occurs:

ErrorException Array to String conversion

Under this things, it send me in vendor director in ResourceRegistrar.php. Here it show me line 410 that is:

$action = ['as' => $name, 'uses'=> $controller.'@'.$method].

How can I resolve this error? Thank you
