Error notice in woocommerce email after update status in webhook

Question

I'm writing a plugin for WooCommerce, everything is working fine but I'm getting a notice error in the emails when the update is being changed in the webhook, if I update the status in process payment function this does not happen.

Even with this notice error the plugin updates the status correctly.

This is how I change the order status in the webhook, is there something I'm doing wrong?

public function webhook() {
    $result = sanitize_text_field($_GET['success']);
    $transaction_id = sanitize_text_field($_GET['transaction_id']);
    $public_transaction_commerce_id = sanitize_text_field($_GET['public_transaction_commerce_id']);

    if($result == 'true')
    {
        $order = wc_get_order($public_transaction_commerce_id);

        $order->update_status( 'completed', 'Pago Confirmado TXID: '.$transaction_id );

        WC()->cart->empty_cart();

        return wp_redirect($this->get_return_url( $order));
    }
    else
    {
        wc_add_notice('El pago no pudo ser procesado, verifique su pedido e intente nuevamente.', 'error' );
        return wp_redirect(wc_get_cart_url());
    }

}

Answer 1

There was nothing wrong with the plugin, the notice was showing because i was in debug mode, so i edited de wp-config to: define( 'WP_DEBUG', false ); and it solved the problem.
