Create view but return 404 error in browser

1

In controllers/CustomerController I create actionShowOrder

public function actionsShowOrder()
{
   $searchModel = new CustomerSearch();
   //$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
   
   return $this->render('show-order');
}

And create show-order.php in views/customer

<?php
    use yii\helpers\Html;
    use yii\widgets\DetailView;
?>

<?php echo "hello"?>

But when I open /customer/show-order its 404 error, but i can open /customer/index /delete and and update (I generated it using gii
what i may wrong

I regenerate the Customer CRUD using GII module and the code work again, what a strange problem

It’s not strange you wrote wrong name for action
actionsShowOrder() instead of actionShowOrder()
