Cannot augment user in UserSession

[kingyue737]

The playground project tries to augment UserSession:

nuxt-auth-utils/playground/auth.d.ts

Line 3 in e344c98

user: {

But user is already declared here:

nuxt-auth-utils/src/runtime/types/session.ts

Line 2 in e344c98

user?: {}

🤔I don't think it is possible to augment an already declared field of an interface.

Type errors in playground:

I am getting this TypeError in my project as well. I've been ignoring them for a while now as I haven't found a solution to this yet sadly...

It seems as if the UserSession type is 'stuck'.
Even the requireUserSession function return-type is not what I expect.

export async function requireUserSession(event: H3Event) {
  const userSession = await getUserSession(event)

  if (!userSession.user) {
    throw createError({
      statusCode: 401,
      message: 'Unauthorized'
    })
  }

  return userSession
}

It throws an error when user is falsy (this includes undefined). So when it does return it should be defined right?
Nope... the type is still user: {} | undefined

(edit) I read microsoft/TypeScript#56528 idk if it is the same issue but it is planned for 5.4.0

I manually remove the user?: {} from node_modules/nuxt-auth-utils/dist/runtime/types/session.d.ts via pnpm patch
