cloudflare dev workers doesnt work after migration from node to bun

[TArch64]

Hi guys. I wanna try bun and migrated my app from node 20 to latest bun version but I my workers stopped working

I have everything in docker and my workers seems to start successfully but every request fails from browser (proxied by nginx) and from worker container using curl. It fails like server didnt start but it does

I keep my workers as monorepo and starts them using run command with filter

bun --filter @minino/worker-uploader dev
# "dev": "wrangler dev --ip 0.0.0.0 --persist-to /cloudflare/data",

here is logs

worker-uploader-1  | @minino/worker-uploader dev:

Vite dev server in another container using same image works fine

I tried to run worker locally without docker and it cannot even start and fails with and without --bun option

Does anyone have thoughts why it dont work?

My config files:

FROM oven/bun:1.1.33-slim
WORKDIR /app

x-app-common: &app-common
  restart: always
  stdin_open: true
  tty: true
  env_file:
    - .env

x-worker-common: &worker-common
  <<: *app-common
  image: minimo-bun
  tty: false
  volumes:
    - ./apps/workers:/app
    - ./tmp/cloudflare/data:/cloudflare/data
    - workers_node_modules:/app/node_modules
    - bun_cache:/root/.bun/install/cache

services:
  worker-uploader:
    <<: *worker-common
    command: bun --filter @minino/worker-uploader dev

upstream worker-uploader {
  server worker-uploader:8787;
}

server {
  server_name local.minino.app;
  listen 80 default_server;
  index off;
  access_log off;

  location /workers/uploader {
    proxy_pass http://worker-uploader/;
  }
}

I dont like having both node and bun runtimes revert changes back to node for now

Found this issue of cloudflare worker sdk repo: cloudflare/workers-sdk#4895
Related bun issue: #8867

Anyone interested in a dedicated cloudflare channel on the bun discord? Running into a lot of problems trying to adopt bun for the system pieces running on Cloudflare. eg.

1. difficult to get the right bun build settings given that cloudflare supports a combination of web and nodejs APIs
2. undici Dispatcher is an empty class, Miniflare fails on worker.dispatchFetch because it's trying to use Dispatcher.dispatch

It also looks like there's been a few steps made towards compatibility in recent days, namely

• Stub performance.markResourceTiming, add PerformanceResourceTiming, PerformanceServerTiming #15341
• Slightly more complete undici polyfill #15360
