Reverse links typescript

Hi there. I'm wondering if it's possible to read a ShoppingCart by it's id and also get all it's ShoppingCartLineItems in one query. I'm trying to avoid making multiple queries to the database. I've had a look at https://xata.io/blog/navigating-many-to-one and https://xata.io/docs/concepts/data-model#links-and-relationships but I'm still not sure how to do this. Schema:

{
  "tables": [
    {
      "name": "ShoppingCarts",
      "columns": [
        {
          "name": "customerId",
          "type": "string"
        }
      ],
      "revLinks": [
        {
          "column": "shoppingCart",
          "table": "Users"
        },
        {
          "column": "shoppingCart",
          "table": "ShoppingCartLineItems"
        }
      ]
    },
    {
      "name": "ShoppingCartLineItems",
      "columns": [
        {
          "name": "shoppingCart",
          "type": "link",
          "link": {
            "table": "ShoppingCarts"
          }
        },
        {
          "name": "productId",
          "type": "string"
        },
        {
          "name": "quantity",
          "type": "int"
        },
        {
          "name": "type",
          "type": "string",
          "defaultValue": "product"
        }
      ]
    }
  ]
}

{
  "tables": [
    {
      "name": "ShoppingCarts",
      "columns": [
        {
          "name": "customerId",
          "type": "string"
        }
      ],
      "revLinks": [
        {
          "column": "shoppingCart",
          "table": "Users"
        },
        {
          "column": "shoppingCart",
          "table": "ShoppingCartLineItems"
        }
      ]
    },
    {
      "name": "ShoppingCartLineItems",
      "columns": [
        {
          "name": "shoppingCart",
          "type": "link",
          "link": {
            "table": "ShoppingCarts"
          }
        },
        {
          "name": "productId",
          "type": "string"
        },
        {
          "name": "quantity",
          "type": "int"
        },
        {
          "name": "type",
          "type": "string",
          "defaultValue": "product"
        }
      ]
    }
  ]
}

What seems to work is:

const record = await xata.db.ShoppingCarts.select([{
    name: "<-ShoppingCartLineItems.shoppingCart",
    columns: ["productId", "quantity", "type"],
    as: "lineItems"
}]).filter({ id: "rec_cno400v3e8os6tplq4jg"}).getFirstOrThrow()

const record = await xata.db.ShoppingCarts.select([{
    name: "<-ShoppingCartLineItems.shoppingCart",
    columns: ["productId", "quantity", "type"],
    as: "lineItems"
}]).filter({ id: "rec_cno400v3e8os6tplq4jg"}).getFirstOrThrow()

However, record doesn't have a lineItems prop. 🤔

Remix v2.8.1 (vite) on Vercel serverless function timeout when making xata db calls

The app is deploying properly and I can't see any issues in the runtime logs on Vercel. The serverless function (Node.js 20x) just timeouts after 60 seconds. Via console.logs I'm pretty sure it's related to a xata query. In the build logs I see the following warnings (not sure if this is related):

WARN: Failed to resolve dependency "kerberos"
WARN: Failed to resolve dependency "gcp-metadata"
WARN: Failed to resolve dependency "socks"
WARN: Failed to resolve dependency "snappy"
WARN: Failed to resolve dependency "aws4"
WARN: Failed to resolve dependency "mongodb-client-encryption"
WARN: Failed to resolve dependency "@mongodb-js/zstd"
WARN: Failed to resolve dependency "@aws-sdk/credential-providers"

I've checked that process.env.XATA_API_KEY and process.env.XATA_BRANCH are defined in the serverless function (via console.log) and they are. I get the xata client like so: export const xata = getXataClient(); Potentiall other relavant parts of the Vercel build logs:

Vercel CLI 33.6.1
vite v5.1.6 building for production...

Vercel CLI 33.6.1
vite v5.1.6 building for production...

I'm using "@xata.io/client": "^0.29.3", in package.json. Any ideas how to further troubleshoot this? Thanks in advance!
