https://github.com/rsheppard-dev/lh-plumbing

To Reproduce

1. Start application in development.
2. Refresh page several times.

Or

1. Load application in production.
2. Occasionally happens when internet connection speed is low or if navigating between routes quickly.

Current vs. Expected behavior

I expect page page to load normally however in development I get this error:

`Unhandled Runtime Error
ChunkLoadError: Loading chunk app/(app)/layout failed.
(error: http://localhost:3000/_next/static/chunks/app/(app)/layout.js)

If I refresh again page loads normally. In production I got a full page of text like this:

Which area(s) are affected? (Select all that apply)

Not sure, App Router

Additional context

I am hosting my Next site on Netlify. This error has happened in production on a MacBook Pro and iPhone 13 Pro using Chrome.

I have also had this happen on Safari.

[ArianHamdi]

We have recently encountered some random crashes when changing routes after upgrading to version 13.5.1. I am not sure about the exact cause, but the page becomes stuck during the route change. In Chrome, it displays an 'Aw, snap!' crash error, while Firefox indicates that the site is slowing down your browser.

We are currently deploying on Amplify AWS.

[khalilsarwari]

This is happening for us in production when leaving the landing page for the following resource:

_next/static/chunks/webpack-8147f10d25df47dc.js
Request Method:
GET
Status Code:
404 Not Found

[rahulknagori]

Facing the same issue in production. Only the pages using CMS/revalidate feature crashes. The issue is most probably in server page.tsx files. Everything works fine in local. This happened when I updated the app to the latest 13.5.5 canary version. Reverted the version to 13.4.1 and now everything works fine even in production.

[max-mayorov]

Having the same issue in production...

[ArianHamdi]

I have found the culprit that is causing the error but I don't know how to fix it easily.

My layout is a server component. My header component in layout.tsx is a server component but that includes a client component for my mobile menu as I use useState to manage the state of my menu. If this is a server component there is no issue but then I can't have a mobile menu functioning.

We are on page router

[rsheppard-dev]

I have changed my hosting to Vercel and so far I haven't had the issue. It appears this is a Netlify issue not a Next issue which I'm glad about cause I love Next but this was making it unusable. Hopefully Netlify fix this. Will keep testing my production app and hopefully it carries on working.

[johnrackles]

So we got this error after upgrading to 13.5.5, in development and deployed to vercel in production. Downgrading to 13.5.4 fixed it

[khalilsarwari]

@huozhi not sure if you guys have seen this yet, but this does seem to be a pretty significant issue (can't upgrade without it since the site doesn't load).
There is some activity here as well: #38507

[jesse-mm]

Same kind of issue here, I have catch-all in my root [...foo] and for me _next assets are not loading but rather loading the catch-all page. Reverted back to 13.5.4 which works for me.

Due to this issue also navigation "crashes" as mentioned earlier in the comments.

[enijar]

@johnrackles's solution is currently the only fix for this. We were experiencing the exact same issue. The issue we discovered was due to encoded dynamic routes [locale].

This URL was what Next.js was requesting which 404'd:
http://localhost:3000/_next/static/chunks/app/%255Blocale%255D/resources/page.js

But manually URL decoding the URL and opening in a new tab correctly resolved the file:
http://localhost:3000/_next/static/chunks/app/[locale]/resources/page.js

We were experiencing this issue on [email protected], but downgrading to [email protected] resolved the issue, so there's definitely been a bug that's been released in version [email protected] or later.

[abilal82]

Had same issue in localhost. I just delete .next folder restart the application and issue resolved. error occurred when i changed routing hierarchy. now its working fine.
NOTE: This is only applied in development mode, I didn't face this sort of issue on production.

[patotoma]

Noticed the same thing as @enijar. The app is trying to load:
.../chats/%255BchatId%255D/page-...
which results in 404

but if I update the url manually to
.../chats/[chatId]/page-...
it works

Current version: 13.5.6

[timhonders]

I think the problem is that the page.js url is double encode

When you url decode:

http://localhost:3000/_next/static/chunks/app/%255Bstorecode%255D/page.js

you get

http://localhost:3000/_next/static/chunks/app/%5Bstorecode%5D/page.js

And it only happens when navigating.

Checked 14.0.0, it still happening

[rahul3v]

Facing the same issue, revert back to v13.5.4

[alvarlagerlof]

I've tried making a reproduction for the issue mentioned in the lower comments here, specifically double encoding of [ and ], but I failed. Since there isn't one in this issue, I would encourage anyone who's also having this issue to make one and share a repo link for it if you are able to. For is, the issue only appears on soft navigations.

[huozhi]

Can someone post a reproduction of this? The origin reproduction in the issue description is 404

[github-actions]

We cannot recreate the issue with the provided information. Please add a reproduction in order for us to be able to investigate.

Why was this issue marked with the please add a complete reproduction label?

To be able to investigate, we need access to a reproduction to identify what triggered the issue. We prefer a link to a public GitHub repository (template for App Router, template for Pages Router), but you can also use these templates: CodeSandbox: App Router or CodeSandbox: Pages Router.

To make sure the issue is resolved as quickly as possible, please make sure that the reproduction is as minimal as possible. This means that you should remove unnecessary code, files, and dependencies that do not contribute to the issue. Ensure your reproduction does not depend on secrets, 3rd party registries, private dependencies, or any other data that cannot be made public. Avoid a reproduction including a whole monorepo (unless relevant to the issue). The easier it is to reproduce the issue, the quicker we can help.

Please test your reproduction against the latest version of Next.js (next@canary) to make sure your issue has not already been fixed.

If you cannot create a clean reproduction, another way you can help the maintainers' job is to pinpoint the canary version of next that introduced the issue. Check out our releases, and try to find the first canary release that introduced the issue. This will help us narrow down the scope of the issue, and possibly point to the PR/code change that introduced it. You can install a specific version of next by running npm install next@<version>.

I added a link, why was it still marked?

Ensure the link is pointing to a codebase that is accessible (e.g. not a private repository). "example.com", "n/a", "will add later", etc. are not acceptable links -- we need to see a public codebase. See the above section for accepted links.

What happens if I don't provide a sufficient minimal reproduction?

Issues with the please add a complete reproduction label that receives no meaningful activity (e.g. new comments with a reproduction link) are automatically closed and locked after 30 days.

If your issue has not been resolved in that time and it has been closed/locked, please open a new issue with the required reproduction.

I did not open this issue, but it is relevant to me, what can I do to help?

Anyone experiencing the same issue is welcome to provide a minimal reproduction following the above steps. Furthermore, you can upvote the issue using the 👍 reaction on the topmost comment (please do not comment "I have the same issue" without reproduction steps). Then, we can sort issues by votes to prioritize.

I think my reproduction is good enough, why aren't you looking into it quicker?

We look into every Next.js issue and constantly monitor open issues for new comments.

However, sometimes we might miss one or two due to the popularity/high traffic of the repository. We apologize, and kindly ask you to refrain from tagging core maintainers, as that will usually not result in increased priority.

Upvoting issues to show your interest will help us prioritize and address them as quickly as possible. That said, every issue is important to us, and if an issue gets closed by accident, we encourage you to open a new one linking to the old issue and we will look into it.

[enijar]

Here's a repro of this error:

https://github.com/enijar/next-load-error-repro

Notice that somehow including this third party script causes the issue:

<Script
  strategy="beforeInteractive"
  src="https://cdn.cookielaw.org/scripttemplates/otSDKStub.js"
/>

[jianliao]

@huozhi Here is a more detail bug reported by me #57829. Please check the Additional context section.

[jianliao]

As a workaround, you can remove beforeInteractive to avoid this issue.

[enijar]

Removing beforeInteractive fixes this issue. This is 100% still a bug as adding beforeInteractive shouldn't cause that behaviour.

[omateusanjos]

Removing beforeInteractive fixes this issue. This is 100% still a bug as adding beforeInteractive shouldn't cause that behaviour.

Bro, you saved our life. Thank you.

[gnoff]

@jianliao thanks for the repro

[huozhi]

We land a fix for #57829 and also the one mentioned related to next/script in v14.0.2-canary.9, please upragde and let us know if your issue is resolved, thanks!

[alvarlagerlof]

I tested the canary locally and can confirm that it the fix works with the Script strategy="beforeInteractive" 🥳

[jianliao]

@huozhi Thanks for the quick fix. I can confirm it works on 14.0.2-canary.10 now.

[feliche93]

@huozhi I am still getting an error on 14.0.2 and also latest canary [email protected]:

For some reason 14.0.1 is working without any errors.

Running pnpm dev everything works with no errors shown.

When I build locally or deploy and navigate from / to /backlink-prospects (packages/frontend/src/app/(app)/(paid)/backlink-prospects) via a <Link/> component I get the following error:

Application error: a client-side exception has occurred (see the browser console for more information).

When I check the console, I see the following:

ChunkLoadError: Loading chunk 3781 failed.

When I refresh the route the page loads without any problem, but a tanstack-table client component is unresponsive, e.g. clicking and everything doesn't do anything.

Let me know if I should open a new issue or can provide any more info.
