Empty page response clears out pagination data

Hi! When using useQuery's pagination I wonder why fetching a page that doesn't return any items clears out the whole data, even though keepPreviousData is set to true.

Here's a sandbox example that mimics an endpoint that does not provide a hasMore field and even though the first pages contain data, asking for a nonexistent page sets the data to []

Is that expected? If so, how would you recommend using the pagination against such endpoints?

keepPreviousData is used to show data from the previous queryKey while you are transitioning to the new queryKey. So yes, this is expected: As soon as the query for the 3rd page resolves, it will be shown. If it has no data, it has no data :)

Thanks for the answer. Looking back at my question I think I was mixing up pagination and infinite loading concepts unnecessarily. 😅
