my worker sends requests to a specific server on the cloudflare network. it's been working for month

my worker sends requests to a specific server on the cloudflare network. it's been working for months and it was working this morning but i just started receiving this error out of nowhere (no deployed code changes in the last few weeks on my worker).

can an employee confirm whether a change was made recently to block access to certain cloudflare ips from workers?

森森@VerseLink (RW)just service binding, you can also invoke it the HTTP way (and not RPC)

LordSilver•11/12/24, 9:36 PM

but that's just a fake HTTP, it's still using same magic under the hood

Isaac McFadyen•11/12/24, 9:48 PM

^ RPC is invariant of transport

Isaac McFadyen•11/12/24, 9:48 PM

You can RPC over a unix socket, over IPC boundaries, or over a network connection

Isaac McFadyen•11/12/24, 9:48 PM

Or even RPC in shared memory as is the case with some apps (see Tauri for example)

... sorry can i vent for a bit?

森

森@VerseLink (RW)•11/12/24, 10:36 PM

or if someone could let me know is there a better solution

森

森@VerseLink (RW)•11/12/24, 10:36 PM

how exactly do you detect if the worker is in dev mode or in production mode?

森

森@VerseLink (RW)•11/12/24, 10:37 PM

it looks like the official solution is to add [env.dev] and add something like ENVIRONMENT = "dev"

森

森@VerseLink (RW)•11/12/24, 10:37 PM

if that's the case....

森

森@VerseLink (RW)•11/12/24, 10:37 PM

then why is the majority of keys "NOT INHERITABLE"

森

森@VerseLink (RW)•11/12/24, 10:38 PM

why?
if it works both in staging / prod and dev, why should i have to copy every single vars under env.dev ?

森

森@VerseLink (RW)•11/12/24, 10:39 PM

i have like an array of vars that define a certain default output

森

森@VerseLink (RW)•11/12/24, 10:39 PM

does that mean i have to copy the whole thing under [env.dev]?

森

森@VerseLink (RW)•11/12/24, 10:40 PM

ok, if that's the case, and I decided that I would change the non-dev vars just because i want a different set of output, does that mean i need to remember to also change env.dev too? I already can see myself debugging only to realize i forgot to change the [env.dev] too because the non dev vars were changed...

森

森@VerseLink (RW)•11/12/24, 10:54 PM

....omg

森

森@VerseLink (RW)•11/12/24, 10:55 PM

now running

wrangler dev --env dev

wrangler dev --env dev

causes service binding to freak out and screams

Cannot access '{functionName}' as we couldn't find a 'wrangler dev' session for service "{service}" to proxy to.

Cannot access '{functionName}' as we couldn't find a 'wrangler dev' session for service "{service}" to proxy to.

森

森@VerseLink (RW)•11/12/24, 11:07 PM

I found the solution

森

森@VerseLink (RW)•11/12/24, 11:11 PM

kind of hacky, not intended; not sure if the wrangler dev session thing is a bug or not, don't care to reproduce it on a more basic setup.
but if brave traveler if you stumble upon this message; instead of using [env], use

.dev.vars

.dev.vars

! yes, it's not meant for local dev and more for secrets; but percisely, you can use this to your advandage that the value of

.dev.vars

.dev.vars

is local to your machine!
(note: this would also cause 'but this works on my machine problem', best to document this and note that include

.dev.vars

.dev.vars

and with an environment variable to indicate it's in development)

not sure why that cf-workers has "node:process" included, but never

process.env.NODE_ENV === 'development'

process.env.NODE_ENV === 'development'

which should be a simple implementation

Isaac McFadyen•11/12/24, 11:53 PM

Because only recently

node:process

node:process

was introduced into the runtime (recent = months/years). If they had added this at the same time, then existing code that checks for

NODE_ENV

NODE_ENV

to determine whether it's running in Workers or Node would break

森

森@VerseLink (RW)•11/12/24, 11:58 PM

oh yeh, great argument!

Well, I still think people would benefit a lot if it's simple to detect what env they are in via something similar, perhaps

process.env.WORKER_ENV

process.env.WORKER_ENV

or a standalone global variable since env is per fetch and not global, so it be also nice to check this can be checked globally sometimes, I guess?

Since a lot of frameworks does things similar to this (for example

app.Environment.IsDevelopment()

app.Environment.IsDevelopment()

in ASP like webservers), I was sort of bummed out that the official way to detect development/staging/prod is via [env], which comes with a whole baggage of concerns like non inherit keys; and also aformentioned bug about not find the session (I'll write up a bug report for it :/)

Got the same issue

RRam Is anyone using Browser rendering at scale? I'm wondering what the pricing looks...

Advany•11/13/24, 11:59 AM

I am, its working pretty good. The durable object isn't that big of a cost factor if you use it at scale. Maximum like $10 dollars a month orso? That you use it like 24/7. As currently there are not session costs?

Out of curiosity, is your ISP Deutsche Telekom by any chance? Or for the users who report having slowness with your worker endpoints

Peps•11/13/24, 2:28 PM

those high connect times make me think it's some weird routing issue and not necessarily Workers

Pato•11/13/24, 8:25 PM

Anyone knows why i have logpush = true and observability on my wranglet toml but still when i deploy i disables it?

Pato•11/13/24, 8:25 PM

And I have to enable it via the dashboard

Pato•11/13/24, 8:25 PM

Im using env and i want to enable it just for mu env.prod environment

Pato•11/13/24, 8:33 PM

How should i define it in my wrangler?

Walshy•11/13/24, 8:35 PM

what's your wrangler.toml look like?

Pato•11/13/24, 9:35 PM

It starts with zone_id, account id, compatibility date and node_compat =true, then i have my envs

Pato•11/13/24, 9:35 PM

But i dont know where to add the observability part and the logpush

CConstantin hey there any ideea about a wasm pdf generator lib (best from html)?

Brett Willis•11/14/24, 4:11 AM

I use Browser Rendering to generate PDFs from HTML. Don't use it at a large scale yet but works fine for me so far.

Cloudflare Docs

Generate PDFs Using HTML and CSS | Browser Rendering docs

As seen in the Getting Started guide, Browser Rendering can be used to generate screenshots for any given URL. Alongside screenshots, you can also generate full PDF documents for a given webpage, and can also provide the webpage markup and style ourselves.

whats the best way to figure out where my cpu usage is? I'm suddenly running into cpu limits for queues (even with a batch size of 1) and ive made all the code changes i can think of to reduce it and it has made no difference

WWalshy Can you send me a build ID?

tadhglewis•11/14/24, 5:46 AM

Did you get a chance to take a look? It seems I managed to get one Worker to pass but the other one still times out cloning the repo

Iaci•11/14/24, 11:27 AM

Hey guys! Any chance I can make an authenticated request fetching an image (from google drive directly through api with bearer access token in the auth header) (not google cloud!) that I can run through cloudflare images to resize it on the fly? saw in the docs (https://developers.cloudflare.com/images/transform-images/control-origin-access/#authenticated-origin) that it is possible but cant get it working

does it live with the worker globally? or it works like KV where its just stored i n1 location and cached
