getConnInfo Cannot destructure property 'remoteAddr' of 'c.env' as it is undefined.

[winston0410]

What version of Hono are you using?

4.4.8

What runtime/platform is your app running on?

Deno

What steps can reproduce the bug?

import { Hono } from "jsr:@hono/hono@^4.4.8";
import { getPath } from "jsr:@hono/hono@^4.4.8/utils/url";
import { getConnInfo } from 'jsr:@hono/hono@^4.4.8/deno'

const app = new Hono();
app.use(async (c, next) => {
  const { method } = c.req;
  const path = getPath(c.req.raw);
  const connInfo = getConnInfo(c)

  console.log('check info', connInfo)

  await next();
});

app.get("/health/readiness", (c) => {
  return c.json({
    status: "ok",
  });
});

export default app;

What is the expected behavior?

Running without error

hi @winston0410 Try using Deno.serve.

Hi @winston0410

As @EdamAme-x said, please use Deno.serve() instead of export default app:

Deno.serve(app.fetch)

The starter template and the website was using export default app, but as you faced it, it might be better to use Deno.serve(). So, I've updated the docs:

Thanks.
