Storefront Api Cart Mutations don't respect language code sent in @inContext

Hydrogen and Storefront APIs

When performing mutations on cart, the returning cart is not respecting the language code sent inside the @inContext.

For example, when creating a cart while sending @inContext with both country and language, the response correctly returns the country but ignores the language code. This seems to happen to all mutations inside the cart, this also happens when buyerIdentity is set to the expected country.

The only way to get the cart with the correct translations is using the cart query, however, this would require us to make 2 requests 1 mutation and 1 query, whenever the cart changes.

Hey @Tiago_Lima :waving_hand: - I did some testing to confirm behaviour, and it does appear that the language code is accepted when I run this mutation for example:

mutation CreateCartWithContext @inContext(country: CA, language: EN) {
  cartCreate(
    input: {
      lines: [
        {
          quantity: 1
          merchandiseId: "gid://shopify/ProductVariant/47123590742038"
        }
      ],
      buyerIdentity: {
        countryCode: CA
        email: "example@example.com"
      }
    }
  ) {
    cart {
      id
      checkoutUrl
      lines(first: 10) {
        edges {
          node {
            id
            quantity
            merchandise {
              ... on ProductVariant {
                id
                title
              }
            }
          }
        }
      }
      buyerIdentity {
        countryCode
      }
    }
  }
}

One thing I did encounter though is that if the desired language isn’t enabled on the country’s market, the language argument won’t be respected. This can be set in the admin at this link: https://admin.shopify.com/store/your-shop/settings/languages

To access the market assignment you’d just want to click the “…” dropdown like this:

Hope this helps - let me know if you’re encountering any further issues, happy to keep looking into this.

Thank you for your response.

I have the following query, removed some private input data and cut some characters to be within limits, but the mutation is still there. In the mutation I set the @inContext(country: $country, language: $language) with values PT and PT_PT.

The following queries/mutation are all to the same cart in the same session.

}

The response to the previous mutation return the following payload, in the extensions, it return the correct country but the wrong language, also the buyer identity is set to the expected country.

{
  "data": {
    "cartCreate": {
      "userErrors": [],
      "cart": {
        "__typename": "Cart",
        "id": "...",
        "attributes": [

        ],
        "checkoutUrl": "...",
        "buyerIdentity": {
          "countryCode": "PT",
          "email": null,
          "phone": null,
          "customer": null
        },

  },

I can always replicate this behavior, the market PT has english as default language but also as spanish, frech and portuguese from portugal which matches PT_PT.

@Alan_G
Hi Alan, I need these translations for a customized customer portal. Is there any way to have the delivery methods in the requested language?
Thanks

I have noticed that same seems to happen to the products inside the orders, @Alan_G.
When fetching the clients orders, the parameters passed inside the @inContext are also ignored when retrieving the list of products.

Hey @Tiago_Lima - thanks for those detailed examples! It is odd that the mutation is returning language: "EN" while queries correctly return language: "PT_PT" for sure.

You’re right that having to make a separate query after mutations isn’t ideal though, but I am glad that you have a temporary workaround at least.

If you are able to share an x-request-id for API responses (from the response headers) where the outputs are showing incorrectly, could you share those here? Once I have those, I can take a look at our logs and do an internal investigation. This does seem like unexpected behaviour though.

@MCP_Webdesign - for delivery methods/shipping rate names, you should generally be able to translate shipping rate names using Translate and Adapt: Re: Translating "Custom delivery description (optional)". - Shopify Community

Out of curiosity, are you setting up the customer portal using the Customer Account UI Extension set up: Customer account UI extensions

Just want to make sure I’m understanding your flow correctly. Hope to speak soon!

Hey @Alan_G thank you for the reply.

Here is a request ID of the mutation that return the incorrect language:
19cea9a6-d56a-40b7-85f3-97bb797996d0-1748944208

Hey @Tiago_Lima :waving_hand: thanks for sending that log reference over - just want to confirm after looking at the logs here, it looks like the country was set to PT, but the language itself was set to EN in the variable input. Just want to make sure that was correct.

If so, just let me know and I’ll look into this more deeply internally. Thanks again!

Hey @Alan_G.

I don’t think that was correct, either way here is another request ID along with the request payload and response payload:

Ah - thanks @Tiago_Lima , it looks like somehow the requested language is changing on our end. Still can’t confirm if this is expected or what might be happening, but this is really helpful, appreciate you sending that my way, I’ll dig into this more internally and get back in touch with you once I have an answer or if we need to do some more troubleshooting with you.
