I registered my domain with cloudflare because the website advertised the ability to host made webpage; i made a website and uploaded it to clloudflare pages as well the site should route through to a custom domain but when clicking to visit site i just get a 404 message

Hi there, I would like to ask for some help with my cloudflare worker. When i make a request to another cloudflare worker of mine that holds a variable with data in it from another cloudflare worker. The data returned is empty, however i make the data request from my browser or api tester, it returns the correct data. It is specifcally when I request the data from a cloudflare worker.

js
import { Router } from 'itty-router'; const router = Router()

order_data = [];

//admin only
router.get("/order", async (req) => {
   return new Response(JSON.stringify(order_data));
});

I'm creating a worker + DO that accept websocket requests. I'm a little bit confused of how do I implement the hibernatable API. Does someone have an example? And also, how do I know that I did it right?

Is it possible to modify request before passing it to binding? Let's say I have code like this on top level worker that sits on https://example.com/edge/backporter

ts
import { Router } from 'itty-router';
const router = Router();

router.get('/edge/backporter', async (request) => {
  request.query = '?foobar' // modify request
  // Set URL to specific URL in other worker
  request.url = '/edge/v1' // Error, cannot set read-only property
  return env.BINDING.fetch(request);
}

And on

BINDING

worker I have router that responds to certain URL only https://example.com/edge/v1

ts
import { Router } from 'itty-router';
const router = Router();

router.get('/edge/v1', async (request) => { ... }

I'd like to make sure request from first worker ends up in

/edge/v1

, but it never does, since I can't change request URL, nor can I

request.clone()

, since then URL would match

/edge/backporter

and not

/edge/v1

Is anything like this possible?

I wanted to raise this formally although I've been discussing it in #1150557986239021106 , as I'm not sure where in the CF stack the issue lies. Basically a single query in my app, among hundreds, sometimes returns rows and sometimes returns this:

{
  command: null,
  rowCount: null,
  oid: null,
  rows: Array(0),
  fields: Array(0)
  ...
}

All other queries work fine, as I say. So I'm sat here refreshing and endpoint and sometimes seeing data and sometimes not (with no code changes). This is happening while running my app locally (with

--remote

) so HD is being used. So I assume this is a HD issue, though perhaps it's at a Workers/Wrangler level for all I know. I could disable HD caching, but then that presumably defeats the point of HD? Any help is greatly appreciated as this is blocking me at the mo! Thanks in advance.

Hi !> I have a question regarding workers and their pricing when connected to a websocket. Assuming my use case is a realtime multiplayer game and I want to synchronize the state between players such as player position, rotation etc. The client sends updates to the websocket server 5 times a second and worker writes to Upstash Kafka for global distribution of the message. In this case can somebody help me, will my worker be billed for all those 5 requests a second so billed for : ``5 * 3600 * 24 * 30 = 12,960,000 ``packets per month ?

After a week of developing a small REST API which was working beautifully, suddenly this error just appeared. Going back to previous verisons of my code doesn't work, neither does reverting to previous wrangler versions, deleting node_modules and reinstalling, restarting machine ... any idea how to proceed?

Hi, after trying with multiple Visa, Master and Amex cards to subscribe R2 service but still getting error. "There was an error processing your card. Please check your details and try again."

We're partly porting over functionality that uses MongoDB for JSON document storage, so I'm looking at the best option for storing this data on Cloudflare (and if not on Cloudflare, what the best storage tool in the ecosystem is). I want to help understand the storage technologies and help understand their pros and cons.

Hello, I'm currently making a React Native app and I'm trying to get/send data to my KVs in cloudflare, however I'm not getting this to work. I'm new to cloudflare and workers in general, help would be appreciated. This is my fetch request currently, I don't know what to put in my worker to communicate with the KVs:

ts
fetch('WORKER_URL', {method: 'GET'}).then((response) => response.json()).then((json) => {
    console.log(json);
  }).catch((error) => {
    console.error(error);
  });

My worker is currently just default with the Response Hello world due to not knowing what to do.

Howdy! I got a report from some of my users that R2 is no longer serving content. Everything from my custom domain is returning a 200 with 0 bytes (even if the file does not exist). For example: https://cdn.btst.io/test.html

I don't know how long this has been happening, but I don't see any evidence reported anywhere? Is this an issue on y'all's side?

I’ve been trying to using DOs for websocket handling, I’ve seen that the message handling function is getting called when I send a message from the front end. However, I also saw that there is no context object being passed to that function. How can I lookup other DO instances in the function that handles incoming websocket messages? Thanks in advance

I have a `.dev.vars`locally with some secrets, and Wrangler is telling me they're available, however in my worker I've tried both

${env.SECRET_NAME}

and

{context.env.SECRET_NAME}

, neither of which is resolving. Does anyone know what might be the issue? Since the documentation mentions both approaches, I am suspicious that either might be incorrect.

I'm using cf-binding-proxy, drizzle ORM, and Sveltekit. I'm using "npx cf-binding-proxy --d1=db" and "npm run dev" at the same time. This is to use HMR of sveltekit. The cf-binding-proxy part continues to rebuild every time the file modifies, making it difficult to access from the npm run dev server. Is there a similar problem or any workaround?

Hello Everyone, I have some issues where I can't upload my file with rclone. This is the error message that I got: 2024/01/11 20:33:16 ERROR : Attempt 1/3 failed with 1 errors and: multi-thread copy: failed to write chunk: failed to upload chunk 4 with 5242880 bytes: SignatureDoesNotMatch: The request signature we calculated does not match the signature you provided.

Feels a bit silly asking this but I keep calling or visiting my function url on my deployed site (like example.com/functions/my-function), but I get a 404 response from my frontend application. What is the correct path for functions once the site has been deployed? Could anything else be happening here?

Hello, I'm trying to wrap my head around how these products integrate. I have pages website and I want to be able to pull data from a R2 bucket in order to be displayed on the Pages site. What is the correct way of doing this? Creating a worker that handles the R2 bucket access and then having the pages site access via api? Or creating a function that access the bucket and forgo the worker? When the worker or page has an R2 binding, I assume secrets are not necessary?

I'm talking about the ones one developers.cloudflare.com/workers/examples. Using

export default

causes the error

Error: No routes found when building Functions directory

I'm using a form action to post to my function

<form method="POST" action="/functions/send-email"

However Wrangler keeps erroring with "No response" My function is:

export async function onRequest() {
  return Response.redirect('/')
}

Please tell me what I'm doing wrong

I'm diving into streaming responses and I see myself writing this:

ts
await writer.write(encoder.encode('<h1>Hello world!</h1>'));

Is this the right way of appending strings or is it possible to remove the

encoder.encode

call of the

TextEndoer

?

I am trying to make this via cloudflare workers. But sadly WebGL does not work in cloudflare. What is the usecase? I have a worker that tries to go to the page and is making a screenshot on canvas on the webpage. This implementation is working for 90% of cases, however when someone uses WebGL (in p5js), the returned image from worker is a white screen. I already have an implementation: https://github.com/kodadot/workers/tree/main/capture Working minimal PoC (on Vercel): https://github.com/vikiival/vercelgl https://dev.to/rainerselvet/serverless-3d-webgl-rendering-with-threejs-4o11 I was sent here from #1110268932788588624 https://discord.com/channels/595317990191398933/1110268932788588624/1191708168489812038

Again a silly question but it's not in the documentation that I could find. When you're running a local dev server with wrangler, it tells me it's recognised the function, and has copied it to some temp folder, but am I able to access it via the web browser locally? I'm trying to debug things and this would significantly close the feedback loop.

Every so often, seemingly appropos of nothing, I get this (attached). This is while developing with the

--remote

flag active. If I quit and restart the server, all is fine. Is this is a known issue, and should I be concerned about this ultimately happening when I host my app for production?

Hello, I use Workers with Queue, but I occasionally encounter the "Exceeded CPU Limits" error. Is it possible to change from bundled to standard or unbound ? I try change to unbound in settings page but I got error "Workers Unbound has not yet been enabled for this account. (Code: 10075)".

We are migrating some features of our to use cloudflare workers, so that we are on edge, and can give response times < 100ms The response times are high, and we were not able to optimize. So, I deployed a hello world example here: https://hello-world.betalectic.workers.dev/ The example I deployed to above url is: https://github.com/cloudflare/workers-sdk/blob/main/templates/worker/index.js Is this what to expect from CF Worker? (So, we just find an alternative?)

Hi Guys I'm very new in cloudflare ecosystem, i just build sveltekit website and deploy it in cloudflare pages and so far it is working perfectly with supabase as a backend. recently i also have a needs where i need to make a rest api, and i try to use hono js and deploy it in cloudflare workers. the questions is how i can put environment variables in my projects? and how i can access it in my index.ts?

Im new to wrangler and i need some help doing this, i have a cloudflare account setup.

I m trying to send emails from a form in a astro static site I m making but I couldn't find a way to make it work. I followed the guide https://developers.cloudflare.com/pages/functions/plugins/mailchannels/#spf-support-for-mailchannels Right now I m not using cloudflare email routing as I m using google workspace, but I suppose it should work anyway, correct? - So i created the

_middleware.ts

file (code on first comment), having

"@cloudflare/pages-plugin-mailchannels": "^0.1.2"

on the dependencies - On the form I added the attribute

data-static-form-name="contact"

- Added includes to my existing spf record so now look like this

v=spf1 include:_spf.mx.cloudflare.net include:relay.mailchannels.net include:_spf.google.com -all

- Generated DKIM Credentials following the guide https://developers.cloudflare.com/pages/functions/plugins/mailchannels/#generate-dkim-credentials - Added to environment variables (see image) - Added the TXT record mailchannels._domainkey (see image) - Added domain lockdown (TXT

_mailchannels

) with both workers domain and my domain as stated here https://community.cloudflare.com/t/introducing-mailchannels-domain-lockdown/523913/5: `v=mc1 cfid=majestico.workers.dev cfid=majestico.it `(and see image) Now when i try to send email from https://majestico.it/contact/ I get the error "Could not send your email. Please try again." Am I missing something? Is there a way to debug this problem and get a significant error? Thanks

Hello! I need to download files that are stored in R2 using CF Workers as a middleman (for auth). Whats the best way to download files from R2 using Workers as the middleman? Files are < 10MiB
