deno quit when exporting oak module

[Srabutdotcom]

Dear team,

I use deno version 1.11.2
and have been trying to export oak module but the app quit without any error message.

import { Application } from "'https://deno.land/x/oak/mod.ts'";
const app = new Application();
export {app}

and then when i call deno run, it is just quit.....

What is wrong?

Can you share the code where you're importing the app?

Can you share the code where you're importing the app?

import {app} from '../start.js'
await app.listen({ 
      hostname: localhost, 
      port: 80})

even before reaching this line, deno quit.
