Wrong Historical Data on 9:20AM every day

I am running a job every 5 minutes to retrieve historical data for the previous 5-minute interval. However, every day at 9:20 AM, when I run the job to get the Nifty open candle data, it always returns incorrect information.

Example on 02/12/2024:
I use the following API call:

historicalData = kiteConnect.getHistoricalData(from, to, id, time, false, true);
from: 09:15:00
to: 09:19:58
time: 5 minutes

Retrieved Values:
Open: 24149.55
Close: 24036.25
Date/Time: Mon Dec 02 09:15:00 IST 2024

Kite Platform Values:
Open: 24140.97
Close: 24037.40
Date/Time: Mon Dec 02 09:15:00 IST 2024

Could you please explain why this discrepancy occurs? What time frame should I use to ensure accurate retrieval of the first 5-minute candle data?
