How to use unstable_serialize for SSR or SSG fallback Next.JS page with SWR 2.0

[SebastienSusini]

Hello, i'm trying to migrate from SWR V.1.* to SWR v.2.*.

My fallback doesn't work and I have the impression that the documentation for the V2, it still shows an example with old SWR key: const { data } = useSWR(['api', 'article', 1], fetcher)
hasn't been updated on this part: https://swr.vercel.app/docs/with-nextjs#complex-keys

Thank's!
