Can i get feedback on this pagination code?

Notes: The code is working well, to my understanding, but i am not sure if thats how its suppose to be. If anyone can give me feedback if its written optimally, or it has flaws, please let me know.

I also attached a picture of the query dev tools

const fetcher = async (url, params) => {
  const res = await axios.get(url, {
    params
  })
  return res.data
}

export default function Inspiration() {
  const router = useRouter()
  const page_size = 12
  const queryClient = useQueryClient()

  const { data, isLoading, isError, isPreviousData } = useQuery(
    {
      queryKey: ['projects', router.query.page, page_size],
      queryFn: () =>
        fetcher('/api/projects', {
          page_num: router.query.page,
          page_size
        })
    },
    {
      keepPreviousData: true
    }
  )

  const tags = useQuery(['tags'], () => fetcher('/api/project-tags'), {
    staleTime: Infinity,
    cacheTime: Infinity
  })

  useEffect(() => {
    queryClient.prefetchQuery(
      ['projects', Number(router.query.page) + 1, page_size],
      () =>
        fetcher('/api/projects', {
          page_num: Number(router.query.page) + 1,
          page_size
        })
    )
  }, [router.query.page, queryClient, page_size])

  if (isLoading) return <Loading />
  if (isError) return <div>error</div>
