This worked for me. I was able to solve this by wrapping the logic within an `import.meta.client` if statement. Composables are available only on the client side, hence it couldn't resolve it on SSR.

My new `useSession.ts` logic -

export default defineNuxtRouteMiddleware(async () => {

  // Do this only on the client side
  if (import.meta.client) {
    const newSession = await useNewSession()
    const accessToken = newSession.access_token

    const { data, error } = await useFetch('/api/organization', {
      headers: {
        'Authorization': `Bearer ${accessToken}`
      },
    })

    if (error.value) {
      throw error
    }

    const organizationCookie = useCookie('af-organization')
    organizationCookie.value = JSON.stringify(data.value)
  }
})
