WeakRef is a relatively new api to land in workers. Try setting your compat date to 2025-05-06 or newer to enable it. I’m not sure exactly which part of your app uses it, but if that’s the only issue it might resolve it!

NNorfeldt did you find a solution for it?

CubityFirst•5/21/25, 12:01 PM

are you able to store CSS in here that the worker can reference?

jonast•5/21/25, 1:57 PM

I've got a simple list of schedules like this in worker:

  "triggers": {
    "crons": ["* * * * *", "*/2 * * * *"]
  },

  "triggers": {
    "crons": ["* * * * *", "*/2 * * * *"]
  },

But when I deploy this, the value of controller.croncontroller.cron inside my worker's scheduled callback is always * * * * ** * * * * - this makes it impossible to differentiate between the two different schedules. Is this a known issue? If so, is there any workaround?

ty, it works. And you know if Rewrites of nextjs are working on this workers enviroment? im migrating from pages. Im trying to use it but it throws 404

I don't know, sorry, I'm not familiar with next.js or open next.

Norfeldt•5/21/25, 7:10 PM

I'm wondering if it's because I setup the proxy and are trying to develop a workflow locally before I deploy it. Did you try binding it to a deployed workflow?

andifined.dev•5/21/25, 7:12 PM

Yes but for my understanding it‘s because the workflow doesn‘t get bundled into the the entrypoint file related to the worker. In my Situation that‘s the error I get.

Norfeldt•5/21/25, 7:15 PM

Guessing the best way would then be to setup a workflow with hono that it can use. Just didn't wanted to make an api and quite newbie to CF (like having trouble understanding the diff between pages and workers since they claim you can deploy a NextJS to a worker which I thought what pages was for)

Ibby | Fk Israel•5/21/25, 7:35 PM

Hey guys does anyone know what happens when cloudflare workers make API calls ?

I'll definitely do that - and likewise please ping me if you solve the issue

andifined.dev•5/21/25, 8:02 PM

So I already did that to be honest, but I don‘t think the way you expect it. I’ve created a separate worker for the workflow and added it as service binding to my astro Applications. Works Like a charm, but could be easier obviously ^^

is there a good guide to hosting discord apps on workers?

Original message was deleted

dave•5/21/25, 10:51 PM

I resorted to just doing fetches in seq. For context, I do about 64 fetches in parallel to endpoints that are usually cached, it's used to create the table in this:

Rahil•5/21/25, 11:13 PM

elo rating and overall ranking. It's for 8 ball/pool. I have a friend who's built a more advanced version of the bot helping me and he suggested using railway to host it, but I found out about workers and wanted to see if workers is a good free alternative or just not the right type of tool for the job. My friend said he's not familiar with workers, so he doesn't know, so I thought I'd ask here. It's going to be the first bot I host, so I don't know if I should be using Workers or something else. If not, I'll just stick to railway

Hard@Work•5/21/25, 11:17 PM

Sorry, I meant how do you get those stats? Do you send them via a command? Does the bot have to keep track of messages sent?

Rahil•5/21/25, 11:20 PM

it's gonna be a command like /matchend [username] or something like that, and the bot will send a message and the other person clicks confirm or deny. When the other person clicks confirm, it will update the database with both people's new elo rating

And what does it compute the actual Elo off of?

HHard@Work And what does it compute the actual Elo off of?

Rahil•5/21/25, 11:28 PM

it's going to be a combination both the players' current elo and win rate. It going to retrieve the current elo and in rate from the database, and update it based on a formula. My friends bot takes into account the number of matches played with the other person, but mine will essentially be the same thing but only with a single round.

hi, can anybody help with this?
For the past few days, some users can’t open our website. They are getting ERR_CONNECTION_TIMED_OUT on our Cloudflare Pages site. I posted about this on the Cloudflare community page: https://community.cloudflare.com/t/my-website-is-not-opening-for-some-users/800642

Original message was deleted

ai.alok•5/22/25, 7:40 AM

Some users have reported that they are unable to access the site.

We’ve tried a few troubleshooting steps that worked for some users, such as resetting their Wi-Fi or connecting to a different network. However, we don’t yet know how many users are affected.

we are not sure why this issue is happening..?

ai.alok•5/22/25, 7:43 AM

we don't have any info about their specific location but certainly all are from India.

ai.alok•5/22/25, 7:44 AM

This is one of our user on twitter.

AubSs•5/22/25, 10:35 AM

Hello, we're getting a few errors 500 when fetching some js/css assets from our Vue SPA App from CF Pages. Assets are deployed. What could be the reason ?

AubSs•5/22/25, 10:38 AM

And it's totally random. Assets sometime are available and a few minutes later, not anymore.

Original message was deleted

ai.alok•5/22/25, 11:37 AM

This is not happening with us but some of other website as well in India.

What can be the real cause?

Hi, how do I change the version of pnpm used in the environment without having to change my build command?

dhkl•5/23/25, 1:21 AM

We just saw some pretty wild stuff. We've been deploying our Next.js on Workers. Just now, we noticed that a much older version (many hours ago) of the site was being served to users

quisi.do•5/23/25, 2:05 AM

Quick question: Would I only ever want to use Workflows for an API call that isn't expected to finish promptly? I have several asynchronous APIs where I want the call to wait until they are complete. I like that workflows encapsulate steps, maintain state, and auto-retry... but I don't want the response to be "Here's an instance ID. Come back later for a response." I want it to actually wait on the response. Are workflows the wrong tool for APIs that are intended to respond quickly, or is there a way to await instance.response()await instance.response()?

Dubz•5/23/25, 2:28 AM

For whatever reason I'm having difficulty finding this again but how does one go about rewriting a URI path to a different file without redirecting/worker script? :meow_stare:

0x146231489231923•5/23/25, 2:27 PM

can ask framework specific question here? wanna ask ques related to react-router, basically how to enable hot reload for cloudflare worker local development?

0x146231489231923•5/23/25, 2:28 PM

wrangler dev

wrangler dev

command with hot reload

00x146231489231923 `wrangler dev` command with hot reload

Max (@rozenmd)•5/23/25, 2:56 PM

looking at https://github.com/cloudflare/templates/tree/main/react-router-starter-template it seems like react-router devreact-router dev should automagically run wrangler under the hood (you might need to clone the template to see whats going on)
