I’m working on a Shopware 6 project and trying to display the quantity of line items in a Twig template /checkout/finish. However, when I try to access the quantity property in the index.html.twig, I am getting empty string. However, this gives correct value in base.html.twig.

Here’s the code I’m using:

{% set count = 0 %} 
{% for item in page.order.lineItems %}
      {% set count= item1.quantity + count %}
{% endfor %}

How can I access quantity of the final checkout in case of

2x Produkt A
1x Produkt B

so that the total quantity I get will be 3?
