useSWRInfinite behaves weird

[ahmadxgani]

in the docs says default of initialSize = 1, however, in the console.log the index is 0, setting the initialSize on option parameter is not change anything

const getKey = (pageIndex: number, url: string, prev: any) => {
  console.log(`${url}?page=${pageIndex}`, prev);

  return `${url}?page=${pageIndex}`;
};

export default function CustomPagination<T extends IProductResponse>({ url, children }: { url: string; children(props: T): React.ReactElement }) {
  const { data, isLoading } = useSWRInfinite<T>((index, prev) => getKey(index, `${url}`, prev), fetcher);
}

ahh it seems initialSize is for amount of request not the number of pagination, for workaround, i manually increment pageIndex +1 to get the index 1 in the first request
