Hi, I’ve started getting this error “Required parameter missing or invalid: items” when adding to cart My theme is debut, my site is littletingles.com My product-template.liquid code is : <div class="product-template__container page-width" id="ProductSection-{{ section.id }}" data-section-id=…

Figured it out myself. If anyone ever has this problem. I had to add: value="{{ variant.id }}"> {{ variant.title }} too line 162 so that the code would look like this: <option {% if variant == product.selected_or_first_available_variant %} selected="selected" {% endif %} {% …

Hi, How did you resolve this issue?

Hi, Yes. But support and theme developers did not help. I started touse the original theme file which ı uploaded it the first time. And it is solved.

I have to say that their actions are so slow, I contacted them for 2 weeks, but no results. I just add the code provided by ThomasKn, and it looks like working well, no errors. I’ll keep testing.

thanks for sharing this method in free, I test on my theme-studio, and it works normally, the Shopify theme support didn’t resolve this issue for me

I am still having this issue and no one can help: Parameter missing or invalid:items [Shopify Error.jpg] Can anyone please help?
