LordSilver•4/29/25, 7:40 AM

interesting. i guess you'll be able to use this directly even without the playground ai? let's say i create a worker with one prompt "search for X product and give me the price", then I pass a list of shops, i would like the worker to use the same prompt for each website in the list so i can find the shop with the cheapest price.

Rui FigueiraOP•4/29/25, 8:22 AM

Yes, playground AI uses workers AI under the hood, so it should be doable. Playwright MCP contributes a set of tools that can be called by workers AI: https://developers.cloudflare.com/workers-ai/features/function-calling/

Is there a way that I could request closed beta access for cloudflare containers? We are currently using gcp cloudrun and have problems getting it to work for us. I'd like to be able to suggest to the team that we try using cloudflare containers instead.

When I try to deploy a worker from the dashboard editor it’s reverting to the hello world default JavaScript. It was working yesterday. I’ve confirmed this in multiple browsers and by creating a new worker and it still occurs.

Max (@rozenmd)•4/29/25, 4:08 PM

that sounds weird - so you're clicking on an existing Worker, then the edit code button, and instead of seeing your code you see the hello world template?

kaelys.js•4/29/25, 4:10 PM

For better clarification, edit code then make some changes and hit “deploy” and the prior deployed version persists and the changes don’t save. Tried in Chrome/safari and new/existing worker and the issue is there.

For now I switched to deploy via wrangler which works fine.

darkpool•4/29/25, 5:06 PM

can multiple workers share the same domain? For example, let's say I have a frontend worker and an api worker. I want my frontend to be at myurl.com and my api to be at myurl.com/api. Is that possible?

Tobias•4/29/25, 5:08 PM

yes using https://developers.cloudflare.com/workers/configuration/routing/routes/

Cloudflare Docs

Routes

Routes allow users to map a URL pattern to a Worker. When a request comes in to the Cloudflare network that matches the specified URL pattern, your Worker will execute on that route.

Hi, I would like to ask: when I add a "noindex" rule to the _headers file for the *.pages.dev subdomain and redirect the *.pages.dev subdomain to a custom domain using Bulk Redirects, will the custom domain still be indexed by crawler bots, especially Google?

kaelys.js•4/29/25, 7:56 PM

Here’s what I’m trying to do and I got it partially working;

I’m not sure where the best place to ask is.

We are a potential enterprise customer (CF) and use GCP. One of the biggest limiting factors for us in signing for enterprise and one of our projects is not being able to run a worker from a specific geo/colo.

It seems to work using a geo steered LB with an inner and outer worker so the execution of the inner worker can be shifted to say LHR instead of SEA (my closest colo).

Is there anything wrong with doing this or a reason why it won’t work?

Chaika•4/29/25, 8:18 PM

I'm not sure what exactly you mean with using LBs in that way, but if you're going to go Enterprise, Cloudflare has a Enterprise only data localization suite that you can use to control exactly which locations can decrypt and serve your requests: https://developers.cloudflare.com/data-localization/regional-services/

Cloudflare Docs

Regional Services

Regional Services gives you the ability to accommodate regional restrictions by choosing which subset of data centers decrypt and service HTTPS traffic.

TomTom•4/30/25, 12:45 AM

So I recently tried building and deploying my backend and front end (node, next and typescript) into a Wrangler Worker. For some reason my worker's page is stuck on my "Loading Session" infinite loop because the /api/auth/session request isn't being made (from the network tabs and from logs). Is there a way I can look deeper into why this is happening?

TomTom•4/30/25, 12:45 AM

I'm a bit lost here

Benjamín Vicente 🇨🇱•4/30/25, 12:48 AM

I just found out that websites with workers + assets tend to be slower than pages on sequent navigations, since assets don't have cache with max-age

Will there be a way to set that assets return with specific cache-control value? It's weird that there isn't an option to add it directly, considering that most projects with frameworks build assets with max-age headers in mind.

Kenneth Solberg•4/30/25, 6:39 AM

After switching from Pages to Workers for my Astro site I can run deploy from local dev and everything works. However when I connect it to the GitHub repo the build fails with this message: "You have to fill in all your /.env environmental variables". Not 100% sure what's missing?

Kenneth Solberg•4/30/25, 6:58 AM

I have public vars in .toml and secrets configured in dashboard. Do i have to configure them in build vars in dashboard as well?

resolved by adding to build vars, case closed

Afternoon,
I have a workers paid plan, for a pro site.
I'd like to enable Workers Logpush for my worker.
If I try to enable it via wrangler.toml I get:

You do not have access to use Logpush. Please ensure it is enabled. If you are an Enterprise user, reach out to your account team. [code: 10023]

You do not have access to use Logpush. Please ensure it is enabled. If you are an Enterprise user, reach out to your account team. [code: 10023]

If i try to enable it with a CURL request I get
{"code": 1004, "message": "creating a new job is not allowed: exceeded max jobs allowed"}{"code": 1004, "message": "creating a new job is not allowed: exceeded max jobs allowed"}
When i try to list all log push jobs I get:
{"errors": [], "messages": [], "result": [], "success": true}{"errors": [], "messages": [], "result": [], "success": true}
I have no Logpush entry in my administrative UI
I am a super administrator.
Has anyone else experienced issues enabling workers logpush for a non-enterprise account.
So far searching cloudflare knowledge base and discord has only yielded suggestion that we could be on an older 'paid' worker plan somehow.
Many thanks in advance if you have any pointers
Apologies if I'm asking in the wrong channel

Workers Logpush

kaelys.js•4/30/25, 3:34 PM

I managed for POC and curiosity to:
- Use a LB with Geosteering to UK and a 100% weighted pool
- Tie the pool endpoint to an “inner” worker say “lhr.domain.com”
- have another worker say “api.domain.com” do a sub request to that worker, the result is that the colo of that worker ends up being “LHC” — most of the time. So the inner worker is executed out of that colo, where without the LB setup it would be executed at least for me generally in SEA or YVR depending ofc.

Should that even work? It’s more of a poc than anything.

The goal here is to utilize workers and the browser rendering api to spider out customers site to scan for multi region compliance (with their permission ofc). We currently use aws serverless for this but a CF solution is in my experience always simpler and more maintainable and also more cost effective.

But unless there’s a decent way outside enterprise we may stick with what we have.

We also heavily use analytics, 30k customers recording page view / consent events. Works great.

The central problem is that we sacrifice full control (such as regional execution of worker, and deciding where analytics data is housed, say EU for GDPR compliance for starters) for less engineering efforts overall.

It’s a tough sell to move up to enterprise (discussions already happened back in Dec) for some on these reasons.

Benjamín Vicente 🇨🇱•4/30/25, 8:05 PM

vite has a assetsDirassetsDir option, ideally cloudflare (via the vite plugin) should add a cache header to all files under that path.

Natan Parmigiano•4/30/25, 8:25 PM

Hey CF Team!

Just got done reading up on the "Simple, scalable, and global: Containers are coming to Cloudflare Workers"

Im truly amazed at the progress and rate of new feature releases!

One question that came up when reading was:

Will there be a maximum wall-clock limit on containers execution for statefull workloads?

We have some jobs that take a while, and for this reason had to be executed outside the CF platform (currently fly.io), the question is, would this new feature be suitable to run a container that, for example, runs some automation steps that take aproximatelly 40 minutes before exiting?

I know its probably early to ask about platform limits, but i'd love to know more

rufi•5/1/25, 12:55 PM

hello!
It seems there is a limit in the number of characters for tagging a worker version (We are using gradual deployments)
is that by design? we append the environment naming in the tag and this create artificial issues where we have to create shorter tags. Where is this documented? Can we suggest to revise this limit?

Walshy•5/1/25, 1:01 PM

it is by design. what is the ideal limit you're looking for?

Walshy•5/1/25, 1:02 PM

You could also use a message to put the env name in, we limit that to 100 chars

mr.niko.la•5/1/25, 7:43 PM

on paid plan, CPUexecution time is 30s?

i have a audio processing worker that uses 3rd party API to scribe 4-15s and i pipe the response to another llm api call that can take 8s all in one worker.

The dead times waiting for api are not counted only the cpu execution time?

how do i see workers total cpu usage time and memory usage time for each call.
I want to make sure my worker is not going to run out of time if i add more llm api cools on the same worker
thx
