Order Printer Template Problem

[Yamade]

Hello everyone, I wrote an Order printer Template last month, and it has been working normally, but it has been abnormal since this month, mainly because it is mentioned in the two places below.

one is:   <td>{{ line_item.variant.barcode }}</td>

one is:  {{ line_item.image | img_url: 'thumb' | img_tag }}

I tried changing browsers and clearing the browser cache, but it still doesn't show up.
