Fetching Options historical data under chart

fetching using below api doc

with below request
{
“symbol”: “NIFTY23OCTFUT”,
“exchangeSegment”:“NSE_FNO”,
“instrument”: “INDEX”,
“expiryCode”: 0,
“fromDate”: “2023-10-08”,
“toDate”: “2023-10-13”
}

data comes empty
{}

what could be wrong here? does this api from options data for specific strike prices ?

thanks
