do you have a favicon.ico inside app dir? if so, move it to a public dir instead

yeah but why would it out of the blue fail deployment.

villainyOP•7/9/24, 4:43 PM

when i never updated any package

villainyOP•7/9/24, 4:43 PM

CF doing changes it prod that breaks our app?

J

James•7/9/24, 4:49 PM

You know we don't generate that function. It's the Vercel/Next CLIs that wrongly generate an ISR function for a favicon.ico file placed inside the app directory instead of just moving it to the static assets directory

J

James•7/9/24, 4:50 PM

If they didn't, it wouldn't be an issue and it would be treated like the static asset that it is

. So you should put it in the public dir instead of the app dir

Matthew•7/9/24, 11:07 PM

this fixed it for me. but just fyi the standard npm create cloudflare@latest framework next will fail build until you make this change.

J

James•7/10/24, 12:11 AM

ugh

i just saw someone made an issue for it as well and it's because of a new vercel cli release

Has anyone been able to bind email workers to an next on pages api route?

Hi guys has anyone managed to get durable objects running with next pages?

First i get an error mentioning migrations. Then it requires a worker name which is usually auto generated.

Any help would be awesome.

n00b Q: when navigating

workers.api.error.script_too_large

workers.api.error.script_too_large

workers.api.error.script_too_large the idea is that the

_worker.js

_worker.js

_worker.js

_worker.js ~~file~~ *folder in

output/static/

output/static/

output/static/

output/static/ should be less than 1mib (free) or less than how much for paid? the workers documentation says 10mib, and in pages it says 25mib but i think thats referencing static assets only. in discord i have seen conversations referencing 5mib

is it safest to check the

_worker.js

_worker.js

_worker.js

_worker.js folder or to check the

/output/static/

/output/static/

/output/static/

/output/static/ folder itself (minus what is excluded from

?

You can use the next-dev sub-module for local development, and then you should be able to use the same binding from prod and dev via process.env.BINDING_NAME.

If you're on the free plan, you might be hitting the 1mb limit. This can often happen due to chonky dependencies, or you just have a lot of SSR'd routes. You couly upgrade to Workers Paid for a higher limit

Hello Cloudflare community,
I'm encountering an intermittent error in my Next.js application deployed on Cloudflare Workers (next-on-pages). The error occurs in various environments and states:

Error: Disallowed operation called within global scope. Asynchronous I/O (ex: fetch() or connect()), setting a timeout, and generating random values are not allowed within global scope. To fix this error, perform this operation within a handler. https://developers.cloudflare.com/workers/runtime-apis/handlers/
Full stack trace varies depending on when the error occurred, but it typically involves files in the .vercel/output/static/_worker.js directory.

Full stack trace varies depending on when the error occurred, but it typically involves files in the .vercel/output/static/_worker.js directory.

The nature of the error:

Occurs sporadically
Doesn't consistently happen on the same user action
Sometimes occurs when the user signs out
Other times happens when navigating to a different route via side nav

What I've tried:

Reviewed code to ensure async operations are within handlers
Checked middleware and API routes for top-level async operations
Verified next.config.mjs setup for Cloudflare Workers
Ensured fetch calls in components are within useEffect hooks or event handlers

System info:

OS: Linux 6.5 Debian GNU/Linux 12 (bookworm)
Node: 22.4.0
npm: 10.8.1
pnpm: 9.5.0

Key npm packages:

@clerk/nextjs: ^5.1.5
@Cloudflare/next-on-pages: ^1.11.3
@Cloudflare/workers-types: ^4.20240605.0
next: ^14.2.4
react: ^18
react-dom: ^18
typescript: ^5
wrangler: ^3.60.2

Questions:

Are there known issues with Next.js on Cloudflare Workers causing this intermittent error?
Given the sporadic nature, what debugging strategies would you recommend?
Are there specific areas in a Next.js + Cloudflare Workers setup prone to causing this type of error?

Any insights or suggestions would be greatly appreciated. Thank you for your help!
