Workaround:

NUXT_SOCKET=0 nuxt dev

[danielroe]

this should be resolved via #973 in v3.26.3.

let me know if not.

[typed-sigterm]

@danielroe unfortunately it doesn't work, even when NUXT_SOCKET=0 is set.

When NUXT_SOCKET=0 is not set

 ERROR  [uncaughtException] ENOENT: no such file or directory, listen '\\.\pipe\nuxt-dev-8474.sock'

    at processTicksAndRejections (native:7:39)

When NUXT_SOCKET=0 is set

Nuxt can successfully load once, and then:

 ERROR  [unhandledRejection] { [Error: Malformed_HTTP_Response fetching "http://127.0.0.1:51515/_nuxt/?token=MamGLD-MsQZJ". For more information, pass verbose: true in the second argument to fetch()]
  code: 'Malformed_HTTP_Response',
  path: 'http://127.0.0.1:51515/_nuxt/?token=MamGLD-MsQZJ',
  errno: 0 }

and automatically reload, and then:

Afte patching Vite to fix Malformed_HTTP_Response, the socket error still occures; request to reopen

It stop working again after upgrading from v4.1.2 to v4.1.3 though NUXT_SOCKET=0 works. But if I edit content.config.ts to trigger a full reload, a similar error appeared again:
