Looking for feedback on a WAF-false-positive workaround with a Worker

Background - We have a web-mail POST endpoint behind CF Enterprise WAF.
- Fields like html_body, image, compose_cc often trigger false-positives.

Node.JS Compatibility Error...

so following the video, I was expecting this error, but when I go to add that flag, then things have changed a bit. the flag that is suggested by the error, 'nodejs_compat' is no longer in the list, and instead, there are 2 similar available: with or without populate_process_env. see screenshot. I tried both of them, they don't work. I'm still getting that error. any idea?...

responseStreamDisconnected errors when making 6+ sub requests in worker

We are using ctx.waitUntil() API to make sub requests to send metrics/logs to DataDog, and when there are 6 or more requests, the request/response that is being returned is truncated. When looking at real-time worker logs, the outcome field is set to "outcome": "responseStreamDisconnected", . There are no other errors that are present. The format we are using to send metrics is ctx.waitUntil(async function() { return await fetch(...)});. The individual requests all function correctly, and I can reproduce this error by enabling any one of them, but if they are all enabled together, an error occured. We have the following wrangler.toml config:...

Deployment on Workers build goes fine, but waits until it timeouts

Hi, I have a strange issue that began this morning (Europe time). My Opennext build and deployment goes fine, but the Build box stays "up and running" until the 20 minutes timeout occurs. See the timestamps in the screenshot, it idles for 7 minutes even if the build is done and deployed. Normally some more lines appeared after the "Current version ID": ``` Success: Deploy command completed...

cacheEverything: true vs Cf-Cache-Status: DYNAMIC

Hi all, I have 2 zones on 1 account. Both have very similar Cache Rules, where effectively Cache eligibility evaluates to "Eligible for cache". Then I have a Cloudflare worker deployed to both zones, which contains piece of code: ``` const response = await fetch(requestUrl, {...

Queue "send" method hangs, binding is set it up and queue is exist.

Hey there. For some reason even though binding config is set for the queue, env.QUEUE.send(message); hangs in worker. but sending manual message over dashboard to queue just works fine. what may be the issue? In local everything is fine, in production, when pushing manual message through dashboard to the queue everything also just works fine, and queueHandler picks the message as it should be, but when it comes to sending message from worker to queue with send() method it hangs forever. binding is surely in the settings and I call exactly how the binding is set it up via env, so it is env.EMAIL_QUEUE.send() in my case....

Update name in Wrangler configuration file to match deployed Worker #1

when I deploy a wrangler without name=“x”, it generates a pull request, however I don't want to put a name as the repo is used for multiple workers and it generates several pull requests per hour. (You have a pull request pending to accept. Please accept the changes before your next deployment to avoid compilation failures), how can I remove this behavior.

How to stream responses and return a known content length?

I'm using workers as a thin proxy with a little bit of logic between object storage (s3 in this case, but in the future likely r2) and clients. I'm wondering how to support sending data back with a content length header but without buffering the full object in memory? When I return a response with a stream, workers transforms the response to Transfer-Encoding: chunked and removes the Content-Length header to conform to the http spec. There's a great http client (object_store) I'd like to support with this proxy, but it requires content length headers. When i asked there about transfer encoding chunked support they said nope (https://github.com/apache/arrow-rs-object-store/issues/340#issuecomment-2849485808). Any suggestions?...
