Debugging advice when trying to deploy sveltekit to netlify: Cannot find module './llhttp/llhttp_simd.wasm.js' from '/opt/build/repo/.netlify'

Site name: mevorach

When I try to deploy my new sveltekit project to netlify, I get this error message:

8:06:56 PM:   Error message
8:06:56 PM:   A Netlify Function failed to require one of its dependencies.
8:06:56 PM:   Please make sure it is present in the site's top-level "package.json".
​
8:06:56 PM:   In file "/opt/build/repo/.netlify/functions-internal/render.js"
8:06:56 PM:   Cannot find module './llhttp/llhttp_simd.wasm.js' from '/opt/build/repo/.netlify'

Not sure why this is happening, I’ve also tried doing locally β€œnetlify build” and I receive the same error log.

What’s happening? it looks like a bug.
Another person reported this.

Hi @elron,

As discussed in the helpdesk, this appears to be something with Svelte than Netlify. For others who come here, here is where it’s being discussed:
