Cart attribute value from the "input.graphql" returns NULL in a "cart checkout validation" function

Hi, I’m having problem retrieving cart attribute value from the “input.graphql” in a “cart checkout validation” function.

My site is using the new checkout system and I developed a custom extension-only app for customizing it.

There are several extensions in the app. One of the extension is a “cart checkout validation” function.I find that it the cart attributes in the input.graphql are all returning null value. It was working fine (has value) until yesterday.

and I’m not sure why:

Some observations:

  1. I am very sure I did not touch the code and the same piece of code was returning values before.

  2. After checkout, I checked that the order indeed has all of the cart attributes in the order details in admin panel.

  3. Other extension types (e.g. “delivery_customization”, “ui_extension”) in the same app are using the same cart attributes just fine.

  4. I created another “cart checkout validation”, it cannot get the cart attributes also.

  5. I tried disabling/enabling the checkout rule and even reinstalled the whole app, but it does not help.

It seems to me that only the cart attributes in the “cart checkout validation” input are not returning value.

The extension is on api_version = “2023-07”.

My input.graphql:

query Input {
  localization {
    language {
      isoCode
    }
  }
  buyerJourney {
    step
  }
  cart {
    attrAddressType: attribute(key: "address_type") {
      value
    }
    attrAddressPrefill: attribute(key: "address_prefill") {
      value
    }
    deliveryGroups {
      deliveryAddress {
        address1
        city
        provinceCode
        countryCode
        zip
      }
    }
  }
}

In the function:

const addressType = input.cart.attrAddressType?.value; // Returns NULL
const addressPrefill = input.cart.addressPrefill?.value; // Returns NULL

We have same issue, that work fine until yesterday. Today, I got null :flushed_face:

i had the same problem.

But it seems like Shopify don’t support this problem.

I have the same problem with it. Maybe it just happened recently

Hi folks,

Will investigate this issue today to see if there’s been a change on our side that has caused this. I’ll report back asap!

Hi @Liam

Any updates?

Can you confirm the issue lies on Shopify’s end or not?

Sorry for urging, but this function is crucial in my site’s checkout logic.

Hi Slasw7 - it does appear the issue is on Shopify’s side. Our developers are looking into a fix at the moment.

Appreciate your patience here!

This problem just happened 7-8 days ago. But in this morning, I rechecked and it came back, and now it’s working. I don’t know why, maybe Shopify just updated something?

Thanks for your information @nhtbao101 , I turned the function on just now and it came back too.

Hi folks!

Our team shipped a fix for this recently so you shouldn’t be seeing this error moving forward. Please let us know if any of your stores are experiencing this.

Hope this helps,

Thanks Liam, it’s working like a charm.

We are still facing this issue for the last couple of days. Any one else facing the problem now

Hello Liam,

i’ve the same issue in my store which is based on Checkout and Customer Accounts Extensibility and we want to develop a delivery customisation function based on the cart attribute.

query RunInput {
  cart {
    handles: attribute(key: "hideHanldes"){
      value
    }
  }
}

we are passing the the handle in the cart attribute with key hideHandles .

the output of the function is

{
  "cart": {
    "handles": {
      "value": "list of the hideble handles"
    }
  }
}

but when we want to get the details of the handles value is returns null

const hideHandles = input.cart.handles?.value; || returns null

Hi @Liam ,

We are still experiencing the same issue with the Cart checkout validation API despite using the latest API version, 2024-01.

Could you please help us investigate why this is happening?
