Checkout validation function query input variables

Technical Q&A
1

Hello, i’m trying to use checkout validation function with query input variables as it described in the docs
https://shopify.dev/docs/apps/functions/input-output/variables-queries

First of all, there is absolutely unclear information about how to find ownerID. But as i’ve reed on the community forum - Shop is the owner.
But it doesn’t work, i see metafields in the shop, but inAnyCollection filter still return False, when True is expected

Here is a quick sample for it
Query Input (run.graphql)
query RunInput($protectedCollectionsIds: [ID!]) {
cart {
lines {
merchandise{
__typename
… on ProductVariant {
id
product {
id
inAnyCollection(ids: $protectedCollectionsIds)
}
}
}
}
}
shop{
protectedCollectionsIds: metafield(namespace: “$app:nifty-bridge”, key: “protectedCollectionsIds”){
value
}
}
}

Function config(shopify.extension.toml)

[extensions.input.variables]
namespace = “$app:nifty-bridge”
key = “protectedCollectionsIds”

MetaieldsSet input
{
key: “protectedCollectionsIds”,
namespace: $app:${METAFIELDS_NAMESPACE},
ownerId: shopifyShopGId,
type: “json”,
value: JSON.stringify({ protectedCollectionsIds }),
}

Output
i can receive protectedCollectionsIds in the shop metafields

shop{
“protectedCollectionsIds”: { “value”: “{"protectedCollectionsIds":["gid://shopify/Collection/477600842047"]}” }
}

But inAnyCollection in input still False for the product

If i will set default value for $protectedCollectionsIds from metafields
query RunInput($protectedCollectionsIds: [ID!]=[“gid://shopify/Collection/477600842047”])

inAnyCollection will be True, as expected

Can someone help me to figure out how to work with it?
I’ve tried with discount functions and it works as expected.

Well apparently it’s not yet possible to use input variables in the checkout validation, see here.
I have a similar issue where I’m setting a metafieldsSet with shop id and a JSON but my variable input is marked as null where its working well with discount.
