Describe the Bug

Observed behavior

I am not able to run my pages functions locally using Wrangler CLI.

I am running on macOS Sequoia 15.0 but I've seen the same error on Ventura, I've also tried multiple earlier versions of wrangler but they all seem to behave the same way.

Wrangler tries to bind to 192.168.1.146:8788 which is a weird default (I dont use a wrangler.toml file in this example). If i force it to use --ip '127.0.0.1' the command starts just fine but no requests come through, the logs are completely empty.

Expected behavior

At this point I just want to see my hello world working.

Steps to reproduce

Command

wrangler pages dev . --log-level debug

Folder structure

.
└── functions
    └── hello.js

hello.js is the standard hello world:

export function onRequest(context) {
  return new Response("Hello, world!")
}

Please provide a link to a minimal reproduction

No response

Please provide any relevant error logs

 ⛅️ wrangler 3.80.0
