The current file is a CommonJS module whose imports will produce 'require' calls

I don't know what's causing this.

The current file is a CommonJS module whose imports will produce 'require' calls; however, the referenced file is an ECMAScript module and cannot be imported with 'require'. Consider writing a dynamic 'import("elysia-session")' call instead.
  To convert this file to an ECMAScript module, change its file extension to '.mts', or add the field `"type": "module"` to 'c:/Users/shadow/Desktop/Coding/shadow-cookie-clicker/server/package.json'.ts(1479)

  import { sessionPlugin } from 'elysia-session';
import { MongooseStore } from './store/session';
import Elysia from 'elysia';
import { client } from './db/db';

new Elysia()
  .use(
    sessionPlugin({
      cookieName: 'session', // Optional, defaults to "session"
      store: new MongooseStore(client!, 'sessions'),
      cookieOptions: {
        httpOnly: true,
        sameSite: 'lax',
        secure: true,
      },
      expireAfter: 15 * 60, // 15 minutes
    })
  )
  .get('/', () => 'Hi')
  .listen(3000);

Nvm had to change from "nodenext" to "node" and it went away.

Reopening since that did not fix it. I opened other files and errors all over the place.

Yeah I created a brand new project and everything seems to work as expected! Thank you!
