I have the same problem, I have already tried different methods, but nothing helped.

Fixed in v8.0.3

@webfansplz I use Nuxt Devtools and this package comes with Nuxt itself. How do I update the package in this case?

@webfansplz I use Nuxt Devtools and this package comes with Nuxt itself. How do I update the package in this case?

Try to use pnpm.overrides to bump the deps in package.json:

{
  "pnpm": {
    "overrides": {
       '@vue/devtools-applet': ^8.0.3,
       '@vue/devtools-core': ^8.0.3,
       '@vue/devtools-kit': ^8.0.3
    }
  }
}

I use npm😅

UPD: overrides with a 8.0.3 version helped.

I have this exact issue with my Nuxt 4 project. But using just this fix still doesn't fix it

}
}
}

However, It turns out when i regress my vue-router from 4.6.3 (latest as of Oct 25, 2025) to 4.5.1 (version before i upgraded) it works just fine. Hope this can helps someone!

Apparently npm has a similar function too, so you don't have to switch to pnpm just for this.

  "overrides": {
    "@vue/devtools-kit": ">=8.0.3"
  }

this is a problem in NodeJS version 25, reverted to version 24.10, and then the problem was fixed.

Rolling back to version 8.0.1 resolves the issue.
