Laravel 8: Array to string conversion while calling route:list

I have a resource controller which is ArticleController and I want to call this controller in web.php, so I coded:

use AppHttpControllersAdminPanelController;
use AppHttpControllersAdminArticleController;

Route::namespace('Admin')->prefix('admin')->group(function(){
  Route::get('/admin/panel', [PanelController::class, 'index']);
  Route::resource('articles', [ArticleController::class]);
});

Then I tried the command php artisan route:list to check the routes but I get this error message:

ErrorException

Array to string conversion

So why this error occurs, how can I fix it?

Answer

Route::resource is expecting a string for the second argument, not an array.

Route::resource('articles', ArticleController::class);

Remove the call to namespace for the group, you don’t need any namespace prefix because you are using the Fully Qualified Class Name, FQCN, to reference the Controllers.

Route::prefix('admin')->group(function () {
    Route::get('/admin/panel', [PanelController::class, 'index']);
    Route::resource('articles', ArticleController::class);
});
