Quick addition for why I'm out of my depth here.
I can make it work for a simple change like 'when flow runs add "Hello World" to the product description.
{
"query": "mutation { productUpdate(input: {id: \"{{product.id}}\", descriptionHtml: \"Hello World\"}) { product { id } } }"
}
But what I really want to do is use a capture statement above that to construct a description from the metafields on the product.
So as not to overcomplicate things I'm testing this with a metafield called prods.short_desc which is a multiline text field. I create a new variable called 'new_description' using capture that should pick up the value of this MF which I then put into the mutation.
{% capture new_description %}
{%- for metafields_item in product.metafields -%}
{%- if metafields_item.namespace == "prods" and metafields_item.key == "short_desc" -%}
{{ metafields_item.value }}
{%- endif -%}
{%- endfor -%}
{% endcapture %}
{
"query": "mutation { productUpdate(input: {id: \"{{product.id}}\", descriptionHtml: \"{{new_description}}\"}) { product { id } } }"
}
When run this flow will say 'succeeded' every time but it doesn't actually make any changes. Bit odd and just wondering if this is something I'll never be able to get work or if in theory it could.
