Edge runtime for crypto functionality different from Node.js

I am trying to build a solution using Telegram oAuth. This requires some small amount of crypto transformation for validation from Telegram's servers. Recommendations which work use Node.js' crypto methods. I was able to convert these to crypto.subtle equivalents. Unfortunately, these crypto.subtle functions create different results when using Node.js vs. Cloudflare's Workers edge runtime. If anyone has suggestions, I would appreciate it. Below is my TypeScript code. ```typescript // Node.js original code: const key = createHash('sha256').update(BOT_TOKEN).digest()...

Worker route not working

Hey, I've created a worker and want to have dynamic subdomain based routing like - *.app.domain.com. I did everything and it's working in local, but in live it's created the route and all but it's not able to be browsed. ```ts import { Hono } from 'hono'...

Trigger worker build from webhook

I'm using Cloudflare Workers to deploy a website built with Astro. I have setup the gitlab integration and when I push changes to the repo, it creates a new build and deploys it. My question is: Can I also trigger a build from the CMS I'm using through a webhook or similar? I've searched the on multiple places in the docs but couldn't find anything that answered this question....

Support for Ubuntu 20.04 LTS - workerd compatibility with GLIBC 2.31

I'm running Cloudflare Workers on Ubuntu 20.04 LTS, which ships with GLIBC 2.31. When trying to run the local development server (workerd), I'm encountering compatibility issues as workerd requires GLIBC ≥2.32. While I understand there are workarounds (using miniflare, Docker, or upgrading Ubuntu), many developers and organizations still use Ubuntu 20.04 LTS as it's supported until April 2025. Are there any plans to provide workerd binaries compatible with GLIBC 2.31 to support Ubuntu 20.04 LTS users? This would help developers who are required to stay on LTS versions for stability or compliance reasons....

Multiple assets bindings within a single worker

Hi, is 1 worker restricted to having 1 assets binding? I want to serve up different UIs with different ACLs that I apply in my worker & dispatch based on route dynamically but the assets binding in wrangler.json doesn't appear to be an array like other bindings typically are. I understand why that doesn't work when 'run_worker_first' is ever false but certainly when it's true it could be allowed. I just want to double check that this is indeed a limitation of static assets currently.

No log display after using static assets

I'm trying to convert a project I wrote in JS to TS, but when I made the changes, there were no more logs on the worker's log page, and even the request records themselves (such as log records like "GET URL") were not displayed. However, when developing locally or debugging with the web editor, the logs are normal. Does anyone know why? https://sub.schwi.workers.dev/ 我正在尝试把我用JS写的项目改为使用TS，但当我修改完成后，在worker的日志页面就再也没有日志了，甚至不会显示请求记录本身（例如“GET URL”这样的日志记录），但是本地开发状态下或使用网页编辑器调试时，日志却是正常的，有人知道这是为什么吗？ any more information needed, please reply, thanks...

Client disconnected

I have observed multiple instances of Client Disconnected invocation errors on my Worker. As I understand it this is caused by the client disconnecting (link) . All my requests come from the same source and 99.5% of them are successful. Each call also takes no more than 2 seconds to execute attached is a sample request which never finished executing. How do I recreate this and fix this?

Question about workers-mcp and "Unsupported content type: undefined" error

I've been experiencing issues using my deployed mcp servers from Claude Desktop. When I make an http request to the server, the server returns a json object with the expected format. When I try to call a tool in my Claude client, and can see from the logs using wrangler tail that a successful post request was made. However, no matter what I try, I keep seeing a "Unsupported content type: undefined" error. Does anyone have any experience building mcp servers using workers-mcp and know the proper...

Workers Plan stuck on Free Plan - Cannot upgrade to Workers Paid

I was on a Workers Paid plan some time ago, then downgraded it, and now I want to enable it again. I can't do this because of a Workers -> Plans state bug. It says "Your current plan" on the Paid plan, which is not true - I disabled it a while ago. Can someone unstuck me from this situation? I don't have any unpaid invoices. On March 15th, I issued a case for support without an actual response (just a general auto-response that solves nothing). Case number: 01429354

Extremely High Wall Time (900k ms) in Cloudflare Queues + Browser Rendering

While developing a Cloudflare Queues consumer worker integrated with Browser Rendering (@Cloudflare/puppeteer), we observe abnormally high wall time (~900,000 ms) despite normal CPU usage. The worker functions correctly but appears to hang due to potential asynchronous blocking. ```typescript // consumer worker/index.ts import puppeteer, { Browser } from '@cloudflare/puppeteer';...
