Describe the Bug

With this schema.ts, drizzle-kit pull produces a malformed relations.ts

• schema.ts

import { integer, pgTable, text, varchar } from "drizzle-orm/pg-core";
export const users = pgTable('users', {
  id: integer(),
  first_name: text().notNull().default(''),
  last_name: varchar().notNull().default(''),
});

• malformed relations.ts

import { relations } from "drizzle-orm/relations";
import {  } from "./schema";
