ES6 Module Syntax TypeErrors with minimal example

[MexHigh]

I've tried using this minimal example mentioned in the README file:

import { Router } from 'itty-router'

const router = Router()

router.get("/", (request, env, context) => {
    return new Response("Test")
})

export default {
    fetch: router.handle
}

But when running wrangler dev and hitting the / route, the console shows this error:

However, the route returns the correct result "Test".

How do I get rid of these errors?

// 404 for everything else
router.all('*', () => new Response('Not Found.', { status: 404 }))

// 404 for everything else
router.all('*', () => new Response('Not Found.', { status: 404 }))

Yeah, that request for the favicon.ico is certainly triggering that, but it appears to also be on the 200... I'll look into this one!

In addition to the catchall 404 at the end mentioned above, I often have something like this toward the top of my router worker:

const HT_NC= {status: 204};

  .get('/favicon.ico', ()=> {
    return new Response(null, HT_NC)
  })

Of course, you could also return a valid icon if you prefer.

Closing this as answered!
