I have these models: . So I've created an abstract Realty class and Apartment entity class which inherits Realty.

Data source:

import "reflect-metadata";
import { DataSource } from "typeorm";

import Address from "./entity/Address";
import Building from "./entity/Building";
import Item from "./entity/Item";
import Terms from "./entity/Terms";
import Apartment from "./entity/Apartment";
import Listing from "./entity/Listing";

export const AppDataSource = new DataSource({
  type: "sqlite",
  database: "database.sqlite",
  synchronize: true,
  logging: false,
  entities: [Address, Building, Item, Terms, Apartment, Listing],
  migrations: [],
  subscribers: [],
});

import { AppDataSource } from "./data-source";

AppDataSource.initialize()
  .then(async () => {
    console.log("Inserting a new user into the database...");
  })
  .catch((error) => console.log(error));

When I run src/index.ts, I get these errors:

PS D:\Documents\_Igor\Projekti\_Master\express-typeorm-real-estate-listings> npx tsx src/index.ts

    at async DataSource.initialize (D:\Documents\_Igor\Projekti\_Master\express-typeorm-real-estate-listings\node_modules\typeorm\data-source\src\data-source\DataSource.ts:263:13)

Why do I get this error? Are abstract models not supposed to create a table in the DB?
