useSWRInfinite fetch data multi times with page=0

[IRediTOTO]

Hi, i have a simple SWR like this

 const { query } = useRouter()

    const { data, setSize, size } = useSWRInfinite(
        query.categoryId
            ? (pageIndex, previousPageData) => {
                  console.log('previousPageData', previousPageData)
                  console.log('pageIndex ', pageIndex)
                  if (previousPageData && !previousPageData.length) {
                      console.log('return null')
                      return null
                  } 
                  return `/api/category?page=${pageIndex}&limit=8&category=${query.categoryId}` // SWR key
              }
            : null,
        query.categoryId ? fetcher : null
    )

But I get page=0 called multi times when I click to load more button

Did I do something wrong?

Hi! This is currently the expected behavior, see discussions in #1401.
