Incorrect response in flow API

API
, ,
1

when I call the flow API for a deal with some query parameters such as

https://api.pipedrive.com/v1/deals/{}/flow?start=0&limit=500&api_token=********&all_changes=1&items=change,dealChange
image

In the response, i am getting more_items_in_collection as true and next_start as 500, but when I call the API again by updating the start value to 500, I am getting an empty result,

Can you please guide me through what the issue is here?
