Delay in fetching data for the current minute in Futures API

Hello, I have a question about the /fapi/v1/indexPriceKlines endpoint. When I send a request there, I often don’t receive all the data in the response. For example, the current minute has already started, and 15 seconds have passed, but there is still no data for this candle in the response. The case is as follows: at the timestamp 2024-02-22 17:38:15.848, when I made a request to the URL, I received the following response:
So, the last candle closed at 2024-02-22 17:37:59.999, and there is no data for the candle that opens at 2024-02-22 17:38:00.000. Could you please advise on how to obtain this data without such a significant delay of more than 15 seconds?
