`dev` fails with a websocket redirect error

[viraptor]

🐛 Bug Report

Environment

• operating system: macos
• output of rustc -V: 1.47.0
• output of node -v: v14.15.1
• output of wrangler -V: 1.12.3 / master
• contents of wrangler.toml

name = "service_id"
type = "webpack"
account_id = "..."
workers_dev = true
route = "some_domain.net/*"
zone_id = "..."

kv_namespaces = [
  { binding = "KV", id = "...", preview_id = "..." }
]

Steps to reproduce

wrangler dev

What did you expect to see?

Service to start up

What did you see instead?

thread 'tokio-runtime-worker' panicked at 'Failed to connect to devtools instance: Http(302)', src/commands/dev/socket.rs:30:14
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
👂  Listening on http://127.0.0.1:8787
Error: panic

This is triggered in src/commands/dev/socket.rs:28 / wrangler::commands::dev::socket::listen::{{closure}}

Unfortunately due to tokio-tungstenite returning only the status, I don't know exactly what the contents are. It may be related however due to us using access authentication on the domain. If I print out the url wrangler is trying to connect to (https://some_domain.net/cdn-cgi/workers/preview/inspector?f_workers_preview_token=...) and try to curl it, I can see:

< HTTP/2 302
...
< location: https://....cloudflareaccess.com/cdn-cgi/access/login/some_domain.net

which I expect is the same redirect wrangler sees.

I was able to work around this issue by not simultaneously specifying both zone_id and workers_dev when running wrangler dev.

A configuration like this works:

name = "service_id"
type = "webpack"
workers_dev = true
account_id = "..."

kv_namespaces = [
  { binding = "KV", id = "...", preview_id = "..." }
]

[env.prod]
workers_dev = false
route = "some_domain.net/*"
zone_id = "..."
