got that error trying to setup rpc service from one worker to another.
anyone know if that is related to setting up the worker as a es module?

Yeah I got it working. What architecture would you guys say is best for a saas using cloudflare only services

how do I change the location of

.wrangler

.wrangler

so that all the packages in my monorepo share the same database?

Is the Cache API supposed to work inside vitest environment? It doesn't seem to - caches.default.match()caches.default.match() always returns undefined.

If you are using Hibernation, then yes you are only billed when processing a message. Though note that Durable Objects bill on Duration, not CPU Time

Another worker is the client that connects to a durable object that acts as the server. Basically I'm doing pubsub as the official Cloudflare product still isn't open. I'm asking how the billing works on the client side and not the server.

Client Pricing: One Request per invocation, plus any CPU Time you consume

Hello, I’m Allie!•5/16/24, 9:03 AM

But only while processing. Keeping the WS open shouldn't be billed, though note that after about 30s you aren't guaranteed it won't be evicted

Hello Cloudflare lovers! I just wanted to share a little worker snippet that I'm using to display a book cover given a title and author. It helps me display book covers for over 20k books without having to upload any images! https://gist.github.com/jamesflores/85e9777d5ca076b2d29312a31754003e

neoney•5/17/24, 9:11 AM

:woe: why

neoney•5/17/24, 9:12 AM

its nice to avoid callback hell

neoney•5/17/24, 9:14 AM

and to conditionally enter

neoney•5/17/24, 9:16 AM

hmm i see the reason for not implementing is just that its complicated and error prone

neoney•5/17/24, 9:16 AM

¯\_(ツ)_/¯

neoney•5/17/24, 9:16 AM

i guess ill have to do that

neoney•5/17/24, 9:41 AM

I guess I can use this as an alternative to that weird code to make it a bit simpler

export function withChildLogger<T>(
  bindings: Bindings,
  fn: (logger: Logger | undefined) => T,
  options?: ChildLoggerOptions,
): T {
  const logger = getLogger()?.child(bindings, options);

  return logger ? loggerStorage.run(logger, () => fn(logger)) : fn(logger);
}

  options?: ChildLoggerOptions,

  const logger = getLogger()?.child(bindings, options);

  return logger ? loggerStorage.run(logger, () => fn(logger)) : fn(logger);
}

I am uploading a worker using

wrangler deploy

wrangler deploy

and getting this error

  workers.api.error.unknown [code: 10013]

  workers.api.error.unknown [code: 10013]

. If I remove

upload_source_maps = true

upload_source_maps = true

from wrangler.toml it starts working correctly. This used to be working before.
Are there any issues with source maps uploads right now?

avogadro•5/17/24, 1:28 PM

I just checked the above and this is not limited to just one worker, its affecting all of our worker deploys. Same symptom, commenting out the

upload_source_maps

upload_source_maps

makes the upload work.

Short version - you can't. If you're relying on the User Agent, those can easily be changed. (I'd also generally discourage blocking based on a users OS)

Hi! I'm working on a discord bot that i'm running on workers. The same code executed locally works, but on a worker it gets a CANCELED outcome and I'm struggling to understand why. There's a not of helpful info attached to it, nor am I abel to find any documentation related to it.
What causes the outcome to be CANCELED?

sherlock•5/18/24, 8:30 PM

I think I found out why - I added some waits to retry the rate limited calls, and that increases my CPU time way beyond the free limit of 10ms. (Not the ideal way to do it, I know. I'm exploring Workers so this is fun

)

Unsmart•5/18/24, 8:41 PM

A wait/setTimeout doesnt use CPU time, what does use CPU time is parsing the data from KV (or from the discord api) so the larger the value the more CPU time it uses. Local dev doesnt have any CPU limits thus it works fine no matter the size

Unsmart•5/18/24, 8:42 PM

And KV doesnt really have rate limits so I highly doubt the calls to KV are ever being retried but the 1st call will succeed
