Hi, I am unsure why this is failing, but there might be an incident or issue?

Workers build queued with no other builds going on

I noticed my build is in queued status (which it never has been before), but I don't have any other builds going on. Why would it be queued? I also canceled and tried to rebuild it (it's auto triggered with code changes to github) but it still says queued. Any ideas why this would be happening?

Worker Service Binding not working

Hello, we are trying to call a function of workerB like in the service binding demo article but get an error on Worker A:

ERROR: env.WORKER_B.myFunction is not a function.

ERROR: env.WORKER_B.myFunction is not a function.

The service binding is

{binding="WORKER_B", service = "worker-b-stage"}

{binding="WORKER_B", service = "worker-b-stage"}

and the worker b has: ```export default class extends WorkerEntry point { async fetch(..){..} ...

Non-production branch deploy command

I'm starting to use workers as I'm adding workflow support to an application I'm serving with pages. I'm working on getting prod and no-prod environment alignment and I'm seeing some oddities when i'm deploying the worker for a PR. it seems to be running the "Non-production branch deploy command" which I have set to a pnpm script that runs this wrangler deploy --config workers/sync/wrangler.jsonc -e preview workers/sync/index.ts and passes the "-e preview" to send this to the preview environ...

Static asset file limits

Hi there! I opened a thread in #pages-help earlier this year about file count limits: https://discord.com/channels/595317990191398933/1361914707430080513 We're moving away from Pages to a Worker, and workers docs state the existing rate limits (20k files max) are still in place for Static Assets. I'm just checking in to see if that is still a hard limit, or if the limit can be increased on request? ...

Network Connection Lost on Fetch but Fetch not Attempted

Hello, I'm trying to send large content from workers and I'm getting a network connection lost error when attempting to send anything above roughly 100Mb. I don't appear to be getting any requests on the receiving end, so I am thinking my worker isn't even attempting to send the request at all. Is there some limit I'm hitting on outbound request size from a worker? ...

does CF workers include any kind of sortable Request ID like ULID/UUIDv7 into the request context?

Hi, I'm trying to improve logging in in R2 by generating an Request ID. Does Workers has any kind of Request ID included in the request context so I can save a few ms of generating an UUIDv7. This is really crucial to our system, since we are saving auditing data into R2 data catalog.

Invalid Account ID" Error (ERROR 9426)

I am experiencing a persistent "Invalid Account ID" error (ERROR 9426) when attempting to deliver images via Cloudflare Images using a Worker on my domain, mrlipx.com. I have been troubleshooting this extensively without success, and it appears the issue lies outside of the Worker's code logic. My Cloudflare Images Account Hash is: HUDbG83RTduFMklKurMDw The exact error message I receive is:...

How to paste into the web code editor?

Attempting to paste into the web code editor just shows the "No code actions available" message. Is pasting just not allowed for the web editor? Why is that?

Smart Placement

I have three Workers apps (2 SSR/fullstack; 1 SPA) which connect to a Worker "service" that makes the API requests to the external services they need. The service is a WorkerEntrypoint and the app Workers connect to it via Service Bindings and make RPC calls to it and it calls the API endpoints. The users are mostly in South/East Africa but the origin servers are in Germany/Ireland. The reason I did the architecture this way was thinking that by enabling Smart Placement on the service it'd be moved close to the origins while the apps ran on the Workers near the users in Africa (or the US while we're developing it). However, the dashboard says "Your Worker has not received enough requests to make a placement decision". Production (with no real users) has gotten 455k requests in the last month. Dev (with US traffic from us developers) has 680k+ in the last moth. What's "enough"? ...

Hot reloading with Sveltekit and npx wrangler dev - is it possible?

Hi team, I'm using Svelte5 - and would love to use npx wrangler dev to develop quickly. Did some research and apparently it does support Hot Reloading, however, I've never managed to get it working. Does anyone have any insights or know if this is possible or not?
