useSWRInfinite failing while revalidating on focus.

[ssurana2]

Hi,

I am using a JWT token in fetcher which refreshes in every 5 minutes. The initial request works as it is expected but when revalidation on focus runs again after 5 minutes, the fetch calls fail because the JWT token inside the revalidating fetch call is not getting refreshed. But when I click and make a new request it works fine again. I am assuming that the fetcher instance is stored initially and the same instance is then used when running revalidation thus the JWT token not being updated.

Example code:

const fetcher = useCallback((url: string) => {...}, [jwt]);

const { data } = useSWRInifinite((index) => {
  // returning url with pagination params
}, fetcher);

Any idea how I can fix this?
