why is id "undefined" in better-sqlite?

[bingomanatee]

with this table construnctor

export const testAutoIncrementTable = sqliteTable('testAutoIncrementTable', {
  id: integer('id').primaryKey({ autoIncrement: true }), // Auto-incrementing
  name: text('name').notNull(),
  value: real('value').notNull(),
});

I get this table definition:

 CREATE TABLE IF NOT EXISTS "testAutoIncrementTable"
            (
                id number NOT NULL PRIMARY KEY DEFAULT undefined, name string NOT NULL, value number NOT NULL
            )

if I( then add records:

Drizzle autoincerment sql: BEGIN DEFERRED
Drizzle autoincerment sql: SAVEPOINT `  _bs3.   `
Drizzle autoincerment sql: INSERT OR REPLACE INTO testAutoIncrementTable (name, value) VALUES ('test1', 1.0)
Drizzle autoincerment sql: INSERT OR REPLACE INTO testAutoIncrementTable (name, value) VALUES ('test2', 2.0)
Drizzle autoincerment sql: RELEASE `    _bs3.   `
Drizzle autoincerment sql: COMMIT

i get

Drizzle autoincerment sql: select "id", "name", "value" from "testAutoIncrementTable"

---- readAll is  [ { id: 'undefined', name: 'test2', value: 2 } ]

ids are set to undefined not an autoincrement number.
