You mean this is the Pages Functions?

juanferreras•3/21/24, 9:18 PM

we've been adopting next-on-pages recently and it's been working really, really great (kudos to Dario/James/any other contributors I might be missing!)

(on a somewhat similar note to the messages above) I did want to know if either of you had any methods to reliably profile timings in Cloudflare workers – we were surprised to see that:

const t0 = Date.now();
const data = env.KV.get(key);
const t1 = Date.now();

const t0 = Date.now();
const data = env.KV.get(key);
const t1 = Date.now();

const t0 = Date.now();
const data = env.KV.get(key);
const t1 = Date.now();

const t0 = Date.now();
const data = env.KV.get(key);
const t1 = Date.now();

seemed to be reporting

XXX ms

XXX ms

XXX ms

XXX ms in lab conditions even on cache hits (where in a plain worker we see

XX ms

XX ms

XX ms

XX ms_. Then we realized it wasn't KV but rather the first IO we had (and with the CF Workers security measures, we understand we could be measuring things before that I/O that just wait for the I/O to tick?)

I'm not sure about workers because I don't use Workers, I just know that Smart Placement can cause internal errors with Pages. You can try your setup though, I'm not sure if it only happens with Pages functions or if it also happens with static assets

I have a question. If we were to deploy a server side NextJS app to pages, is there a list of originating IP addresses that app would communicate with or a way to get a list of IPs from our deployment that can be whitelisted on another system we have?

Someone correct me if I'm wrong, but the IP's of outgoing requests from Workers ought to match Cloudflare's ips's https://cloudflare.com/ips but just because a request is coming from that IP doesn't mean it's legitimate traffic. There's some good info here https://news.ycombinator.com/item?id=26690388

Hi, I'm the tech lead of Cloudflare Workers.This article contains several misunderstandings.If a Cloudflare customer has configured their origin server to respond only to Cloudflare IPs, then they MUST also verify that the "Host" header on any request actually matches their domain name. If they do not verify the Host header, then anyone can sign...

Hey, I’m trying to find a solution for hosting with next-on-pages a full slug translation i18n (ex: fr/blogue, en/blog). Looking for a solution without the use of a middleware like amannn/next-intl does, the only viable I found right now is svobik7/next-roots copying folders on build. Any other ideas or examples your guys are aware of? 3 days of searching now and It seems complicated..

J

James•3/23/24, 5:08 PM

You could maybe use next.config.js rewrites, but that could end up being pretty laborious

J

Jeff•3/23/24, 6:22 PM

Hey guys, how might I troubleshoot an: "Error code: 1000" error for a next on pages project? It uses pages router, and the /api route throws status code 403, with a plaintext response of "error code: 1000". Works locally with wrangler pages dev. The logs do not make it to the log tail, so seems its before my app

J

Jeff•3/23/24, 6:25 PM

I see online that 1000 implies I'm pointing to a cloudflare ip in some way, but this is just a pages.dev/api/ route, so im not sure how

J

Jeff•3/23/24, 7:30 PM

It seems that passing of specific

x-vercel-*

x-vercel-*

or

cf-*

cf-*

headers was triggering this. The headers were coming from

next/headers

next/headers

and may have gotten mixed around by all the trpc context switching going on in the T3stack boilerplate. If anyone runs into this I just wrote code to strip any of those headers being sent on UI requests

E

Erisa•3/24/24, 1:49 PM

It was likely the cf-connecting-ip header

How do I go about debugging this? As I can run this locally with

is the right command, if so I'm running into a bunch of 500 errors that I really can't figure out)

✘ [ERROR] Your worker created multiple branches of a single stream (for instance, by calling `response.clone()` or `request.clone()`) but did not read the body of both branches.

(?) could this be the issue?

nah that's an annoying warning because of a response.clone in react i think it is

or it's a request.clone that they do somewhere, can't remember. i just recall dario found the line in react where it comes from

that would suggest an error is being thrown IIRC, you could tail a deployment and see if there's any useful logs?
