Error: Inline regex not working in koa-router (Unexpected "(" at 10)

I am trying to use an inline regular expression in a koa-router route parameter, but I am getting an error. Here’s my code:

import Koa from 'koa';
import Router from 'koa-router';

const app = new Koa();
const router = new Router();

router.get('/hello/:id([0-9]{5})', (ctx) => {
  const id = ctx.params.id;
  console.log(id);
  ctx.body = `Hello ${id}`;
});

app.use(router.routes());
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});


Error:
      throw new TypeError(`Unexpected ${nextType} at ${index}, expected ${type}: ${DEBUG_URL}`);
              ^
TypeError: Unexpected [ at 11, expected END: https://git.new/pathToRegexpError

Older versions of koa-router works with this. I tried reinstalling everything. Tried installing the latest for everything.

This error occurs in the latest version 13.0.1. Tried to downgrade to 11.0.2 or 12.0.1 and solved the issue.

In package.json change: "koa-router": "11.0.2" and remember to remove the "^"

I have not check detailed on the document, maybe this changed to other syntax?
