JSONData<T> should not return a Partial type

[maxfi]

Describe the bug

JSONData should not be a Partial of the record’s type

To reproduce

/**
   Schema:
   
   ```json
    {
      "tables": [{
        "name": "Merchandise",
        "columns": [
           ...
          {
            "name": "description",
            "type": "string",
            "notNull": true,
            "defaultValue": ""
          }
          ...
        }]
      }]
    }
    ```
   */

  const record = await xata.db.Merchandise.select(["description"]).getFirst();
  if (!record) throw new Error("No merchandise found");
  console.log(record); // Type: const record: SelectedPick<MerchandiseRecord, "description"[]>
  console.log(record.description); // Type: (property) description: string
  const serialized = record.toSerializable(); // Type: const serialized: JSONData<MerchandiseRecord>
  console.log(serialized.description); // Type: (property) description?: string | undefined

Expected behavior

The type of serialized.description should be the same as record.description. Ie, the type should be Type: (property) description: string not Type: (property) description?: string | undefined.

Software version

• @xata.io/client: ^0.29.3
• typescript: 5.4.2
• $ xata --version : @xata.io/cli/0.15.10 linux-x64 node-v18.17.0

Additional context

Current workaround:

const record = await xata.db.Merchandise.select(["description"]).getFirst();
if (!record) throw new Error("No merchandise found");
const serialized = record.toSerializable() as unknown as (typeof record)
