Reproduction

Iv been struggling to reproduce this on smaller projects, but its definitely only a problem on RC 12, RC 11 works fine.

I noticed on larger projects that when requesting the router page nuxt RC12 produces a header overflow error on h3. which then causes the entire dev server to crash

Describe the bug

it seems sometimes when going to routes we get a header overflow error from h3.

this also seems to only be a problem on nuxt dev, nuxt generate seems to handle everything ok for some reason

You may try disabling early hints. Please see #15189 if that is relevant to you.

export default defineNuxtConfig({
  ...
  experimental: {
    writeEarlyHints: false,
  },
  ...
})
