NestFactory.createApplicationContext run successfully but never exit. How to shutdown app gracefully?

I love this idea so much, Thanks to that, you can take advantages of the Nest framework everywhere, including CRON jobs and even build a CLI on top of it., but stuck.

create app context and invoke marketService.test()

import { NestFactory } from "@nestjs/core";
import { ApplicationModule } from "../../src/app.module";
import { TradeModule } from "../../src/trade/trade.module";
import { MarketService } from "../../src/trade/services";

const run = async () => {
    const app = await NestFactory.createApplicationContext(ApplicationModule);
    const marketService: MarketService = app.select(TradeModule).get(MarketService);
    marketService.test();
}

run();

marketService.test() log message successfully, but script never exit. how can I use i in CRON?
