Hello
roc crash on first http request with any basic-webserver example

for example with this code:

app [Model, server] { pf: platform "https://github.com/roc-lang/basic-webserver/releases/download/0.7.0/wBzpUZavn70SpVSh8GpfH0YaXM3ydMbu8s4eAiPC-Ko.tar.br" }

import pf.Stdout
import pf.Task exposing [Task]
import pf.Http exposing [Request, Response]
import pf.Utc

Model : {}

server = { init: Task.ok {}, respond }

respond : Request, Model -> Task Response [ServerErr Str]_
respond = \req, _ ->
    # Log request datetime, method and url
    datetime = Utc.now! |> Utc.toIso8601Str
    Stdout.line! "$(datetime) $(Http.methodToStr req.method) $(req.url)"

    # Respond with request body
    if List.isEmpty req.body then
        Task.ok { status: 200, headers: [], body: [] }
    else
        Task.ok { status: 200, headers: [], body: req.body }

I have this error:

Listening on <http://127.0.0.1:8000>

Are you using roc built from source? or a nightly? for that version of the webserver you probably need the TESTING nightly or roc built from main.

It's not normally the case that versions are like this -- we have just had a bug for a couple of weeks we want to resolve before upgrading the releases to nightly.

The latests releases are always kept in sync and tested together (along with all the website examples), so if you're using a pre-release things are unstable.
