Snippet returning 404 when fetched from worker

Hi, I have a worker that I'm using to develop a snippet (have to use worker so that I can profile performance). Due to being a worker I'm using it via hitting a route with it and providing the path of the response it's modifying via a query parameter, however it seems that this URL returns a 404 response, when hitting it from my browser / wrangler locally returns a valid response.

Routing not working on root domain

I'm setting up a worker on a brand new cloudflare account. I have tested that it works. I also set up a test subdomain and router for that and found that the worker works properly. However, when I set up routing for the root domain, the routing doesn't seem to be working. I confirmed that the worker is not getting called in the metrics and logs. ...

Concurrent workflow instances limited at ~120 instead of 4500

So I was observing workflows dashboard this morning, because I made a quite significant changes to my worker last night. I was expecting approximately 400 instances per minute that are spawned from a parent workflow that are batched into 4 groups, 100 per 15 seconds. I was expecting all to be ran on their given interval. But instead of all been completed, I see a huge number of workflow instances being queued; then it accumulated at least 1 thousand of instances. I observed it on time, and turned off the scheduler 'cron'. Hence stopping the ability to generate more queued instances. I am not sure if there is anything from worker that is limiting the ability from achieving the ideal concurrent instances, or any other reason, please help Also the workflow dashboard also been extremly slow. And whenever I push any new debugging changes, it failed the build...

Assets serving tail latency

I ship static assets with my worker, in run_worker_first=false mode with custom _headers. This is a low volume worker (hundreds of requests per day). I'm seeing massive tail latency, TTFB of over a second (vs 40ms on a warmed up worker in my closest colo). Is this normal & to be expected?...

[OpenNext] Unexpected errors and warnings in Cloudflare build logs

Hey folks, I'm migrating from Next-on-Pages to OpenNext and started seeing some errors and warnings in my Cloudflare build logs that previously only appeared during local development. It seems like the app is being built in a "local" context, even after pushing to prod. For example, errors like:

Cannot access [service binding method] as we couldn't find a `wrangler dev` session for service "[service name]" to proxy to.

I'm familiar with these locally, but why would they occur during preview/prod deployments? Has anyone else faced this issue?...

Is there a way to make a magic link email through worker?

I am trying to make a auth server, and I am trying to make a magic link at the registeration process to check their email. I tried this API, but since it needs destination_address to be verification email, It didn't fit my needs well. https://developers.cloudflare.com/email-routing/email-workers/send-email-workers/...

puppetteer-core does not work with websockets: "ws does not work in the browser"

So, it looks like somehow, wrangler is picking up the browser implementation of the ws package (https://github.com/websockets/ws/blob/master/package.json). I tried using different WRANGLER_BUILD_CONDITIONS and WRANGLER_BUILD_PLATFORM to fix the issue, but haven't managed to fix it. I'm a bit stuck
