The likely workaround is:

export default defineNuxtConfig({
  vite: {
    define: {
      __NUXT_ASYNC_CONTEXT__: false
    }
  }
})

This bug is back in the version 3.10.0(1), in 3.9.3 it`s ok

Yep same issue here after upgrading to the latest version.

Running on mac as well.

My guess is that you have another Nuxt installation under /Users/<your-user-name>. Try deleting node_modules and package.json with your package manager’s lock file from there.

@and-ratajski You’re right! Removing node_modules from the home folder solved it for the friend of mine. Good catch!

CernyMatej on Jan 2, 2024

I’m pretty sure it’s not a Nuxt issue but is triggered by the mismatch of Nuxt/vite versions.

danielroe on Jan 2, 2024

Just got the issue last week.

In addition to all anwsers above, if you’re using pnpm.

Running pnpm store prune then reinstalling should also work

My guess is that you have another Nuxt installation under /Users/<your-user-name>. Try deleting node_modules and package.json with your package manager’s lock file from there.

If that doesn’t help you can try downgrading your Nuxt version to 3.8.2 and reinstalling it.

Further update:

A reproduction here:

https://stackblitz.com/edit/github-e4atgm?file=app.config.ts

removing import { defineAppConfig } from '#app/nuxt'; from your app.config.ts file seems to also fix this issue.

Hi, I personally wasn’t able to replicate this issue, but my friend has been experiencing it on his MacBook. The nuxt schema version is 3.9.0

Where should I put the workaround?

CernyMatej on Dec 31, 2023

Would you check that your @nuxt/vite-builder version is also 3.9.0?

danielroe on Dec 27, 2023

@leosin Could you please run npx nuxi info or list modules that you are using?
