We have just migrated from react query v3 to react query v4. Official react query document to migrate mentions onSuccess is no longer called from setQueryData.

See below for more details.

https://tanstack.com/query/v4/docs/framework/react/guides/migrating-to-react-query-4#onsuccess-is-no-longer-called-from-setquerydata

There are few places in our app where we call setQueryData from onSuccess callback like below.

const useUpdateTitle = (id) => {
  const queryClient = useQueryClient()

  return useMutation({
    mutationFn: (newTitle) =>
      axios
        .patch(`/posts/${id}`, { title: newTitle })
        .then((response) => response.data),
    onSuccess: (newPost) => {
      queryClient.setQueryData(['posts', id], newPost)
    },
  })
}

Such use cases are mostly while using useMutation hook and none while using useQuery hook.

Is this ok or will this cause any problem?
