Fluent Table API - autoNumber does not work

[AlexAlvarez]

Hello Community!

I have created a table using Fluent's Table API, and the table is created correctly, as well as the "title" column, but it seems to ignore the autoNumber. After reading the documentation, I can’t find what might be happening, so I wanted to ask if anyone else is experiencing the same issue. 

import { StringColumn, Table } from "@servicenow/sdk/core";

export const x_680259_da_demo = Table({
  name: "x_680259_da_demo",
  label: "Demo",
  autoNumber: {
    prefix: "DEMO",
  },
  schema: {
    title: StringColumn({
      label: "Title",
      mandatory: true,
    }),
  },
});

In the logs for the build and deploy commands, everything seems correct — no errors are shown.
