Does anyone know how to resolve this error I'm trying to upload the mtls certificate

Unsmart•1/30/24, 8:33 PM

Sounds like the cert you are passing isnt in a proper format what are you uploading in

Alipio Pereira•1/30/24, 8:39 PM

Thanks, corrected and it worked

Adi•1/30/24, 11:19 PM

Hey all, I converted my worker to use smart placement over 2 days ago. I can see the placement status is set correctly

"placement_status": "SUCCESS",

"placement_status": "SUCCESS",

However, the dashboard says that there is still insufficient data for the request duration metric (there have been over 200 requests in the last 24 hours).

There is one thing I want to clarify, this worker is being invoked from a CF pages backend. So it's a CF worker calling this worker. Does that affect any metric collection? Should I not expect the request duration metric to show up eventually? Or is it just a waiting game?

Adi•1/30/24, 11:20 PM

It's weird because I turned another worker into smart placement last night, it is still at the

"placement_status": "INSUFFICIENT_SUBREQUESTS",

"placement_status": "INSUFFICIENT_SUBREQUESTS",

but it already has data in the graph.

Unsmart•1/30/24, 11:25 PM

How many external requests do you make?

Adi•1/30/24, 11:25 PM

The worker calls D1 quite a few times per request I'd expect (it's a graphql API)

Unsmart•1/30/24, 11:27 PM

I’d assume graphql probably combines them all into 1 query but afaik smart placement doesn’t do any of the “smart” logic when you use D1 and just places it near the D1 instance even if you don’t call it so not sure why it isn’t

Adi•1/30/24, 11:28 PM

Hmm I see. But you're not sure if it would/wouldn't result in metric collection for the request duration graph?

Adi•1/30/24, 11:28 PM

I guess, related question, does smart placement consider requests to R2 an "external request"? And place the worker appropriately?

Justintime•1/31/24, 12:47 AM

Does anyone have additional information on how diagnostic_channel events are “forwarded” to tail workers? What is the mechanism of transit? I’m particularly interested in the security of this transmission.

Adi•1/31/24, 12:57 AM

Question, do workers started by a cron trigger have the same subrequest limit (e.g they can only make 1000 subrequests per invocation?)

Erisa•1/31/24, 1:06 AM

Correct

Erisa•1/31/24, 1:07 AM

Invocation is an Invocation regardless by which method its invoked, whether thats fetch or cron

Adi•1/31/24, 1:07 AM

Right, and that subrequest limit is all inclusive with internal services too right? E.g if I make 1000 requests to KV, then I have no more bandwidth to make requests to something like R2

Erisa•1/31/24, 1:09 AM

I believe that's also correct

Adi•1/31/24, 1:09 AM

Ok, understood. Thanks

dave•1/31/24, 1:09 AM

iirc you can 'get around' the subrequest limit by using service worker bindings

dave•1/31/24, 1:09 AM

I think we do that for one of our Workers that makes a crapton of requests at once

Adi•1/31/24, 1:09 AM

oh really? So those workers have no subrequest limit?

dave•1/31/24, 1:10 AM

they have the same 1,000 subrequest limit

dave•1/31/24, 1:11 AM

if you make 1,000 subrequests to another service Worker that makes 1,000 subrequests, you now have a million requests in total triggered by 1 incoming HTTP request

Adi•1/31/24, 1:11 AM

oooh I see . Got it, very clever XD

Erisa•1/31/24, 1:12 AM

Yeah so each invocation has the same limit but you can invoke a worker from another worker to get another 1k subreqs and "cheat" the system, though you do ultimately pay for more requests and if you recurse too deep you'll eventually run into an error to prevent infinite recursion

dave•1/31/24, 1:12 AM

you could even make a simple Worker that just takes in a list of URLs, and returns a list of responses from each lol

Erisa•1/31/24, 1:13 AM

As an aside you can also make a Worker have a service binding of itself

dave•1/31/24, 1:14 AM

if you go down through only 3 subrequests, aren't you already allowed to make 1 trillion requests? (1000 * 1000 * 1000 * 1000)

Erisa•1/31/24, 1:15 AM

In theory yes but in practice you may find yourself falling victim to anti abuse systems if you try to launch 1 trillion subrequests

dave•1/31/24, 1:18 AM

hah I would expect to be blocked at that scale anyway

dave•1/31/24, 1:20 AM

the cost for 1 trillion subrequests in this example would be $300 right? (1000 * 1000 * 1000) * (0.30/1,000,000)

Shouldn't you also count in cpu time?

Why is this not working on /rewrite.html i get 404 error

export default {
  async fetch(request, env, ctx) {
    let response = await fetch(request)

    // Check if the request URL ends with "test.html"
      // Create a new response with the same content but a different URL
      const newUrl = request.url.replace('/test.html', '/rewrite.html')
      console.log(newUrl)
      response = new Response(response.body, {
        status: 301, // Redirect status code
        headers: {
          ...response.headers,
          'Location': newUrl
        }
      })
    
  
    return response
  },
};

export default {
  async fetch(request, env, ctx) {
    let response = await fetch(request)

    // Check if the request URL ends with "test.html"
      // Create a new response with the same content but a different URL
      const newUrl = request.url.replace('/test.html', '/rewrite.html')
      console.log(newUrl)
      response = new Response(response.body, {
        status: 301, // Redirect status code
        headers: {
          ...response.headers,
          'Location': newUrl
        }
      })
    
  
    return response
  },
};

kian•1/31/24, 9:33 AM

What's the route on the Worker?

vakno•1/31/24, 9:40 AM

domainname/test.html

vakno•1/31/24, 9:40 AM

it is changing the url but i get 404 error on page

kian•1/31/24, 9:43 AM

The Worker isn't involved with /rewrite.html if you don't have a route covering that, so the 404 isn't an issue from the Worker.

vakno•1/31/24, 10:00 AM

What do you mean by that?

vakno•1/31/24, 10:03 AM

I want to achieve changing url from /test.html to /rewrite.html but serving the same content

export default { async fetch(request, env, ctx) { let response = await fetch(request) // Check if the request URL ends with "test.html" // Create a new response with the same content but a different URL const newUrl = request.url.replace('/test.html', '/rewrite.html') console.log(newUrl) response = new Response(response.body, { status: 301, // Redirect status code headers: { ...response.headers, 'Location': newUrl } }) return response }, };

Can you send me the code for `kvworker`, and make sure that the KV Namespace you screenshotted match
