All of my requests are failing when smart placement is turned on with dev server.

Hi, I'm trying out smart placement for worker with dev deployment which serves 0 to minimum traffic. I know that smart placement has analysis process that may take up to 15 minutes, however worker request failing by 100% is something odd if I understood correctly. Is this normal for Dev servers with less traffic? Will it work if I just blindly switch smart placement on for Prod servers? (I'm afraid not) Looking for a help / insight to mitigate this request failures!...

Getting Authentication error [code: 10000] on deploy from wrangler

Hi, since yesterday I am getting a very annoying error. I have a opennextjs worker and I deploy pretty frequently to test, since I don't use the local development and preview. On running yarn wrangler deploy the second step in the script (opennextjs-cloudflare deploy) fails: ```bash Successfully populated cache with 10 assets Creating D1 table if necessary......

Is there a way to view durable objects built in SQL or agent schedule?

I can't see any of the current rows or schedules/crons that are being executed by my agent. Nor can I see the tables for my durable object.

Need help running queue jobs in worker concurrently

Hey there i’ve got a background job that i run for every user, and each job takes at least ~90 seconds wall time. what i want is to run them for all users concurrently, not sequentially. so right now, for testing, i’m adding one queue message per user (say 10 users). i set max_batch_size = 1 and max_concurrency = 50 on the queue. i was expecting cloudflare to spin up multiple consumer workers so jobs don’t block each other....

What's the recommended way to interact with cache from Workers?

Hi team, I’m trying to clarify the best practice for handling cache from Workers, and I’ve noticed two different approaches in the docs: 1. Set config & let Cloudflare handle it — for example, using Cache Using Fetch, where you configure and pass the request through with fetch(). 2. Interact directly with the Cache API — for example, using Cache API , where the Worker itself retrieves or stores content explicitly....

MongoDB errors

I wanted to update my worker removing the old deprecated MongoDB Atlas API, and I read that now Workers should support the MongoDB node.js driver, but I can't seam to make it work. Everything is working fine on my local machine, I set the compatibility flags to nodejs_compat and compatibility date to 2025-05-05, but when I publish the worker I keep getting errors like: ```diff...

Long wall times and short response times

Hey folks, we're seeing a worker with long wall times but very short response times. We're not using context.wailtUntil anywhere, and this is a fairly simple request flow through Hono (which we've now logged the living daylights out of, including in Hono itself). We have a couple of Supabase REST API calls that complete quickly, and we seem to get to the point where we're returning the response within 200-500ms, but we end up with a CPU time of maybe 10-20ms and a wall time of 30s. The worker then gets cancelled, but appears to have correctly returned a response—all very mysterious. Finally, I've tried to hit everything with the dangling promise lint rules in @typescript-eslint and biome, but nothing pops out. With all that said, I'm wondering if anyone knows what might be good to look out for to understand where the wall time is being spent—how do others go about debugging these scenarios?...

Counting Workers requests: difference between charts

On the dashboard, the Workers and Pages page tells me my workers have handled 501K requests this month. But the Billable Usage chart on the Billing page says 4M(!) requests over roughly the same time period. What could explain the difference? 4M can't be right - it's not consistent with database metrics, analytics, etc....
