@Moderator_3
actually i solved it the problem was about how the names of option contracts differ for nifty and banknifty its same but sensex is different i eventually figured it out

i wanted to fetch symbol tokens of sensex options so today was 14th november2024 the day is thursday and technically today is the expiry since tomorrow is holiday so the expiry should be 14nov but in the json file it was
available for 24nov
1st occurence

2nd occurrence

as you can see there was a mistake in the expiry dates
please look into it @admin

import pyotp
from SmartApi import SmartConnect
from logzero import logger


apikey="z1IPZzY0"
username="M52500299"
pwd="1233"

smartApi=SmartConnect(apikey)

try:
    token = "4TZ63NU76235CQV3KFW6HB7A2Y"
    totp = pyotp.TOTP(token).now()
except Exception as e:
    logger.error("Invalid Token: The provided token is not valid.")
    raise e

data = smartApi.generateSession(username, pwd, totp)

if data['status'] == False:
    logger.error(data)
    
else:
    # login api call
    # logger.info(f"You Credentials: {data}")
    authToken = data['data']['jwtToken']
    refreshToken = data['data']['refreshToken']
    # fetch the feedtoken
    feedToken = smartApi.getfeedToken()
    # fetch User Profile
    res = smartApi.getProfile(refreshToken)
    smartApi.generateToken(refreshToken)
    res=res['data']['exchanges']

    #place order

    
    try:
        orderparams = {
            "variety": "NORMAL",
            "tradingsymbol": "NIFTY31OCT24400PE",
            "symboltoken": "99926000",
            "transactiontype": "BUY",

            "stoploss": "0",
            "quantity": "25"
            }
        # Method 1: Place an order and return the order ID
        orderid = smartApi.placeOrder(orderparams)
        logger.info(f"PlaceOrder : {orderid}")
        # Method 2: Place an order and return the full response
        response = smartApi.placeOrderFullResponse(orderparams)
        logger.info(f"PlaceOrder : {response}")
    except Exception as e:
        logger.exception(f"Order placement failed: {e}")
