I'm starting to get HTTP

520 Bad Gateway

520 Bad Gateway

520 Bad Gateway

520 Bad Gateway responses from my Worker which I have not touched deployed in several days. From the logs, the requests don't event seem to reach the worker (no logs or exceptions). Some requests do reach the worker, but POST/PUT/PATCH requests do not and return 520. There is no backend and, responses are served solely by the worker itself. How do I debug this?

This seems to only be an issue for requests via the workers.devworkers.dev domain. Requests via a custom domain route function normally.

does anyone know if workers are still having issues with discord hooks ?

NotJones•8/26/24, 11:52 AM

sometimes I'm not getting notifications sent but i know that the script ran, as it added to my KV

Walshy•8/26/24, 11:52 AM

can you expand?

WWalshy can you expand?

NotJones•8/26/24, 11:55 AM

expand ?

Walshy•8/26/24, 11:56 AM

what is the issue you're actually seeing? have you tried anything to debug? code? any info really that can help

Walshy•8/26/24, 11:56 AM

what "notifications" are these? how are they sent?

post req to discord api

NotJones•8/26/24, 11:57 AM

discord hook yes, using fetch

Walshy•8/26/24, 11:58 AM

ok, have you debugged what discord has returned? workers all come from the same IP so if you don't send a bot token it's pretty easy to be rate limited.

Walshy•8/26/24, 11:58 AM

we use webhooks extensively in here from Workers (see #cloudflare-blog & #cloudflare-status along with other internal channels) so things are running fine

NotJones•8/26/24, 11:58 AM

oh I see

IdkWhatever69•8/26/24, 11:59 AM

iirc there 2 endpoints for discord webhooks
one returns a response based on success
the other just returns 201

IdkWhatever69•8/26/24, 11:59 AM

make sure u sue the first and log it some other manner

NotJones•8/26/24, 12:00 PM

I will try adding a bot token and see if this solves my issue

alternatively, generate yourself with wrangler deploy --dry-run --outdir distwrangler deploy --dry-run --outdir dist

.gwapes•8/26/24, 2:47 PM

Is this a bug? I literally just made the worker and used

npx create-cloudflare@latest testapp --existing-script testapp

npx create-cloudflare@latest testapp --existing-script testapp

.gwapes•8/26/24, 2:48 PM

It also makes the wrangler.toml main be index.ts when the script it downloads is worker.ts

.gwapes•8/26/24, 2:51 PM

Well actually no, it seems to all be a bit messed up

Gear•8/26/24, 4:33 PM

hello, im reading about durable objects and websockets and id like to understand how they differ from websockets in workers
i've previously built a few minigames using ws with tools like soketi where there's one ws server and all clients connect to it, so it's pretty straightforward to communicate with them
durable objects seem to enable a similar experience, where there's only one instance of DO (given the same id)
how is this different from workers and ws server implemented there? would every client connect to a different worker (and thus ws server) being there alone?

Is there a list of possible values in Request.cf.continentRequest.cf.continent?
this page only lists one example, but no comprehensive "these exist" list: https://developers.cloudflare.com/workers/runtime-apis/request/

h•8/26/24, 6:52 PM

I have a worker on example.myname.workers.dev and i created an alias for the worker on my domain, for example ex.mydomain.com. If I curl to the workers.dev it will work normally however if i curl to the alias i will always get "moved permanently". do i need to set up any special rules for this?

h•8/26/24, 6:52 PM

browser normal access works totally fine

.gwapes•8/26/24, 7:22 PM

Are the paid numbers per day as well?

Kavatch•8/26/24, 8:09 PM

Is there any technical documentation on how the wasm file is built and what exactly has to be exposed for it to be a valid wasm for cloudflare and what the zip should look like that is uploaded + where to upload it?

Or do I just have to reverse engineer everything and try to find it out?

Brett WillisOP•8/26/24, 8:18 PM

Seems like this was an outage on the workers.devworkers.dev domain that was returning HTTP

for POST/PUT/PATCH requests? Seems to be resolved now.

Hi, can anyone point me to some documentation for using a Worker to build and deploy to Cloudflare Pages? Trying to convert a Pages Function to a Worker since I only need it to run once a day, but having some trouble wrapping my head around how to use a Worker to deploy to Pages instead of the Function routing I'm currently using.

lifehackerhansol•8/26/24, 10:33 PM

It seems this is the closest I can get to a proper list: https://developers.cloudflare.com/ruleset-engine/rules-language/fields/standard-fields/#ipsrccontinent

which... is a totally different document from the worker docs...

Erisa•8/27/24, 4:07 AM

its almost certainly the same list, the IP info comes from the same place and in the same format regardless if you read it in ruleset or workers

Do you want to trigger a Pages build from a worker or push code from a Worker to Pages?
For the first one you can create a Deploy hook and trigger a new build by calling the URL.

LuchaBeast•8/27/24, 11:14 AM

The gist of my scenario is that I want to call an API that returns a timetable. I only need to call the API once a day to grab the latest timetable. I then want to build a static page which includes an HTML table of the timetable that was returned in the API response. Finally, I want to push that HTML page to the corresponding route in the Pages project.

I have the first two steps down -- calling the API and building the page from the response. It's the last step -- deploying that page to a corresponding route in a Pages project -- that I'm struggling with.

I'll look into Deploy hooks. It sounds like that's what I might be looking for.

hey guys i am currently exploring different solutions to implement a machine learning model in python into my cloudflare stack. my first idea was to have a cronjob in my worker sending an http request to the python app but if i could get rid of an http endpoint i would do it, any suggestions? could queues be a good idea?

NLBO•8/27/24, 3:01 PM

Please do not post your question in multiple channels/post it multiple times per the rules at ⁠#

welcome-and-rules. It creates confusion for people trying to help you and doesn't get your issue or question solved any faster.

is there a similar placement for R2? (I haven't used R2 at all)

dave•8/27/24, 6:27 PM

Any good minifiers and/or prettifers that work on HTML in a Worker?

Cole•8/27/24, 6:28 PM

interesting, you may want to try disabling http3 and/or http2 to origin

.gwapes•8/27/24, 7:34 PM

On the dashboard, if you make a real time logs, log, does it ever timeout or if you keep the window open it'll always show logs for however long it's open for?

Walshy•8/27/24, 7:35 PM

it should timeout after 6 hours
