checkoutBrandingUpsert name field

GraphQL Admin API Troubleshooting

I’m trying to use the checkoutBrandingUpsert mutation to set a custom font for both primary and secondary typography in the Shopify checkout. However, I’m running into an issue when adding a name field for the custom font.

Here’s my current setup:

mutation checkoutBrandingUpsert($checkoutBrandingInput: CheckoutBrandingInput!, $checkoutProfileId: ID!) {
  checkoutBrandingUpsert(checkoutBrandingInput: $checkoutBrandingInput, checkoutProfileId: $checkoutProfileId) {
    checkoutBranding {
      designSystem {
        typography {
          primary {
            customFontGroup {
              name
              base {
                sources
                weight
              }
              bold {
                sources
                weight
              }
            }
          }
        }
      }
    }
    userErrors {
      code
      field
      message
    }
  }
}


QUery: 
{
  "checkoutProfileId": "gid://shopify/CheckoutProfile/ProfileID",
  "checkoutBrandingInput": {
    "designSystem": {
      "typography": {
        "primary": {
          "customFontGroup": {
            "base": {
              "genericFileId": "gid://shopify/GenericFile/FileID",
              "weight": 400
            },
            "bold": {
              "genericFileId": "gid://shopify/GenericFile/FileID",
              "weight": 700
            },
            "name": "Industry Medium",
          }
        }
      }
    }
  }
}

Despite this setup, I’m receiving an error related to the placement or usage of the "name" field. Based on Shopify’s schema, I believe "name" belongs inside the "customFontGroup", but I may be missing something.

Could someone guide me on the correct way to include "name" in this mutation?

There does not seem to be a name field within the customFontGroup.
