What do you mean? There’s no limit on Workers for duration, and you’re only charged for CPU time. With AI workflows, you’re primarily waiting on I/O, so you’ll be using very little CPU typically.

Isaac McFadyen•12/9/24, 3:20 AM

No Kinda? Environment variable changes require a re-deploy of the Worker.

Isaac McFadyen•12/9/24, 3:21 AM

You could technically redeploy the Worker via the Cloudflare API from within the Worker itself, if you really wanted to, but generally other (easier) methods are recommended first, like storing the value in KV.

oh is it I thout it is. So I also have another thing where I am doing a sync between my databases
but the external req can take only 100 items per minute

Ashley•12/9/24, 8:12 AM

Does it need to happen synchronously, before the HTTP response ends? If not, you could use Workflows and do batches of 100 and then a sleep. Alternatively, you could use Queues and publish a message per item and have some rate limiting, but Workflows will be better imo. Only drawback will be you’d need to create sub Workflows at a certain point with the current step limit (e.g. you’d have an effective cap of 51,200 inserts per Workflow)

Anyone experienced "XMLHttpRequest is undefined" error when trying to use fetch?

Bradley•12/9/24, 4:39 PM

Hello, I'm trying to use Browser Rendering to replace a puppeteer ec2 instance, and one difference I've noticed is that in Cloudflare the scrollbars are getting captured when taking a screenshot. I don't see any options or differences from the ec2 side that is different, except for manually setting headless: trueheadless: true in the browser creation in ec2. But from what it looks like Cloudflare should be defaulting headless. Has anyone seen this issue and found a way to work around it? I'm logging out the browser version and seeing Chrome/120.0.6099.321Chrome/120.0.6099.321 , so maybe it's not headless (or it could be "new" headless, we're likely using old headless on ec2). Update I was able to hack this by using an evaluate call to set overflow hidden on html, but would love a better solution.

Does the Workers Logs has free tier as well? On the main Workers page it lists that the free Workers tier supports "200,000 log events per day".

But I'm confused if enabling "Workers Logs" (including Invocation logs) under "Observability" in Worker settings is free or not?

Brett Willis•12/10/24, 10:46 AM

Variables in the global scope can be shared only in the same instance of the same worker (think: same process on same machine). Not between different Workers (with different name).
This typically only occurs when multiple requests reach the same data center within a few seconds, then they may get routed to the same Worker instance.

from what I researching

This (Send functions as parameters) only works with wrangler experimental, until V8 engine supports it officially, am I right?

Is it misleading mate?
Or am i getting it wrong?

It says workers dont support file-based routing.
But i just created a /testing route in my nextjs deployed to workers

And it worked.
So what does this docs meant?

Ashley•12/10/24, 1:50 PM

The matrix is for the core Pages vs Worker compat, so it’s talking about file-based routing with a Worker without a framework - there’s a lot of differences. If you want Next.js specifics, you’d need to compare what OpenNext supports versus what Next.js itself supports.

1984 Ford Laser•12/10/24, 10:30 PM

You mustn't be using hibernation correctly as it shouldn't build up any duration if you aren't sending any messages. Are you calling

Isaac McFadyen•12/10/24, 10:43 PM

As has been said above, something about your framework is pollyfilling fetch -> XMLHTTPRequest. This is not a Workers issue.

We can't help without knowing what framework you're using, and even then we likely can't help. You'll need to talk to the framework authors.

running locally, have had ~5 people test it, but i think this is due to durable object storage

the documentation says websocketclose will be called whenever the websocket closes to clean up storage

async webSocketClose(

i'm curious if i should implement an alarm to do this on an interval

1984 Ford Laser•12/10/24, 11:03 PM

Your issue sounds like something else. It sounds like something else is pinning the server to stay open. I think when it says clean up storage, that's for the server to handle on its own. Having storage after a server is closed won't continue to incur duration charges

1984 Ford Laser•12/10/24, 11:04 PM

Cannot use assets and tail consumers in the same Worker. Tail Workers are not yet supported for Workers with assets
