Empty page in result of searchMoreWithId call

I've encountered an issue with integration with SuiteTalk API. We import some records (Inventory Items) with `search` call and subsequent `searchMoreWithId` calls. We provide conditions to `search` call and receive `search_id` in response. The search result may be large so we fetch every page of result with separate `searchMoreWithId` call specifying both `searchId` and `pageIndex`.

The issue is some calls of `searchMoreWithId` return empty list of records.

Example of such response with empty page:
