Hello chat! I have an inquiry about `ctx.waitUntil`. **I'm trying to use it in my worker to send tw

Hello chat!
I have an inquiry about

ctx.waitUntil

ctx.waitUntil

.
I'm trying to use it in my worker to send two
fetch
fetch
es (a callback response and a followup message from Discord's Bot API, for context).
When I'm running the worker locally it can send both

fetch

fetch

es just fine, but when its running on the cloud, Discord only receives the first request.
Admittedly, I'm not an expert in async programming, but I don't think I've done wrong since its working locally.
Asking on chance that maybe someone has experience with this.
I have a suspicion that I may have used async/await wrongly.

Posting this message is the last thing I'm doing before bed, so sorry if you'd like to see the actual code; I'll post it later if requested.
Simplified code below...

async fetch(request, env, ctx){
  ctx.waitUntil(
    // Wrapping it in a promise worked for someone else
    new Promise(async function (resolve) {
        await runCommand()
        return resolve(undefined)
    }))
  return new Response("Hello World!")
}

async function runCommand(){
  await sendCallback() // Discord only recieves this one
  // do command stuff
  await sendFollowup()
}

async function sendCallback(){ await fetch() }
async function sendFollowup(){ await fetch() }

async fetch(request, env, ctx){
  ctx.waitUntil(
    // Wrapping it in a promise worked for someone else
    new Promise(async function (resolve) {
        await runCommand()
        return resolve(undefined)
    }))
  return new Response("Hello World!")
}

async function runCommand(){
  await sendCallback() // Discord only recieves this one
  // do command stuff
  await sendFollowup()
}

async function sendCallback(){ await fetch() }
async function sendFollowup(){ await fetch() }

async fetch(request, env, ctx){
  ctx.waitUntil(
    // Wrapping it in a promise worked for someone else
    new Promise(async function (resolve) {
        await runCommand()
        return resolve(undefined)
    }))
  return new Response("Hello World!")
}

async function runCommand(){
  await sendCallback() // Discord only recieves this one
  // do command stuff
  await sendFollowup()
}

async function sendCallback(){ await fetch() }
async function sendFollowup(){ await fetch() }

async fetch(request, env, ctx){
  ctx.waitUntil(
    // Wrapping it in a promise worked for someone else
    new Promise(async function (resolve) {
        await runCommand()
        return resolve(undefined)
    }))
  return new Response("Hello World!")
}

async function runCommand(){
  await sendCallback() // Discord only recieves this one
  // do command stuff
  await sendFollowup()
}

async function sendCallback(){ await fetch() }
async function sendFollowup(){ await fetch() }

Why dont you call

waitUntil(sendCallback)
Then
waitUntil(sendFollowup)

Or even better
Use a Queue, waitUntil only runs for 15seconds, so thats may be your problem

snappsOP•11/18/25, 2:30 AM

I figured out what the problem was. There was an error happening inside the waitUntil and that caused it to hang

snappsOP•11/18/25, 2:31 AM

Would like to use queues in the future when I'm more confident in my abilities though

Hey everyone!
I’m trying to build an AI agent using the Cloudflare Agents SDK and connect it to my MCP server. I’ve gone through the official documentation, but I’m having trouble getting everything working. I’m still fairly new to Cloudflare, so I may be missing something obvious.
If anyone could point me to helpful resources or provide some guidance on the implementation, I’d really appreciate it. Thanks!

Hello, does anyone can tell me, how I can notify the user on the frontend, that a new version is deployed

It would depend on what framework you're using (if any)

Isaac McFadyen•11/24/25, 5:04 PM

For example, SvelteKit has https://svelte.dev/docs/kit/configuration#version

Hello Cloudflare developers, I’m new to the Cloudflare ecosystem and I’m looking for an up-to-date, free course that teaches how to build a simple full-stack app such as a to-do list with authentication using Cloudflare Pages, Workers, Cloudflare Auth, and the D1 database. Any recommendations?

I'd recommend starting with NextJS and OpenNext I'm not sure what "Cloudflare Auth" is, but you can use Clerk for development purposes.

maybe they mean cloudflare access? plus i think hono is a better framework to learn for workers

nextjs runs a little slow on workers irrc

Hello everyone — I would like some help with this template: https://workers.new/templates/openauth-template
. On the first invocation, the worker consistently shows very large wall times (sometimes over 40 seconds). This also happens when testing from new clients or browsers on other devices — the first request always faces the same long wall time. I followed all steps and deployed using the Deploy to Cloudflare Workers option and C3, but the issue persists. Any pointers on what I should check would be appreciated. Thank you!

Edit: I noticed the live example only shows a pair of public keys and the one deployed by the tools creates over 192 keys, why?

José Junior•12/14/25, 8:18 PM

Maybe this is a stupid question, but since Cloudflare SQLite-backed Durable Objects query executions are synchronous, what happens if I mix them with other async operations inside this.ctx.storage.transaction? Can I do that? If the async operation rejects/fails and/or throws, will the transaction be rolled back?

@Ven_Dev how did you solve this, please? coding-help
