I haven't got a reproduction working on stackblitz, but here are the steps to do it (windows machine)

nuxi init yarn add h3-session copy paste the config in readme

then go to localhost:3000

The error will show in console

Thats a bummer

Unfortunately it's really hard to debug compiled files on nuxt so I don't even know what the exact cause is
