Module Not Found in Build Production w/ Netlify

[INTERNAL-ERROR]

Describe the bug

After I updated Svelte to the latest update, I encountered an error that I can't seem to overcome when deploying to Netlify, from code written by Sveltekit in the .netlify foldered.

I have all the latest versions of - Svelte, Sveltekit, SvelteKit Netlify Adapter, and llhttp.

Everytime I try to deploy, I get this error:

7:21:11 AM:   Error message
7:21:11 AM:   A Netlify Function failed to require one of its dependencies.
7:21:11 AM:   Please make sure it is present in the site's top-level "package.json".
​
7:21:11 AM:   In file "/opt/build/repo/app/.netlify/functions-internal/render.js"
7:21:11 AM:   Cannot find module './llhttp/llhttp_simd.wasm.js' from '/opt/build/repo/app/.netlify'

I've installed llhttp in the top level package.json. I went digging, and in the file ".netlify/shims.js" on line 3396, it trys:
mod = await WebAssembly.compile(Buffer.from(require('./llhttp/llhttp_simd.wasm.js'), 'base64'));
This is where the error is coming from, I believe.

My code is hosted on replit: https://replit.com/@AcousticTypewriter911/AudreyTk#app
And Github:https://github.com/INTERNAL-ERROR/AudreyTk

Would welcome and advice on how to correct this error. I can "npm run build && npm run preview" without error, this only happens in production.

Reproduction

I have followed every step in how to install Svelte & Sveltekit, and how to run it on Netlify. I'm not sure where I went wrong.

Severity

blocking all usage of SvelteKit

Additional Information

I won't be able to use sveltekit if this error is not fixed.

[elron]

Same happens to me.
I've posted on Netlify forum as well: https://answers.netlify.com/t/debugging-advice-when-trying-to-deploy-sveltekit-to-netlify-cannot-find-module-llhttp-llhttp-simd-wasm-js-from-opt-build-repo-netlify/70397

[codercatdev]

I’ve just had the same thing happen to me, but fixed the issue by using @sveltejs/adapter-netlify directly (rather than via @sveltejs/adapter-auto) and pinning to the previous version of the adapter.

npm add -D @sveltejs/adapter-netlify@1.0.0-next.65

I have the exact same issue, tried your fix bit it didn't work for me, I still get the same error. Is it implemented in the same way as in the docs (https://github.com/sveltejs/kit/tree/master/packages/adapter-netlify#installation) or did you do something else?

[4RSIM3R]

Same here

[wipersson]

Just tried building it locally using netlify build and it works fine. Still the same issue when deploying though, seems to be enviroment related.

I can't netlify build even in local.

Workss!!

[untold-titan]

I fixed this issue by downgrading to version 65 instead of 66. Then followed the normal Netlify tutorial

[INTERNAL-ERROR]

Yep, downgrading to version 65 worked for me.
Soooo, something went wrong in there, and I'll alert the devs. Thanks so much, everyone!
