Hi,
has anyone been able to create a ROBO order for Bank Nifty Options?

Input:
orderparams = {
"variety":"ROBO",
"tradingsymbol":"BANKNIFTY11NOV2139400CE",
"symboltoken": 48607,
"transactiontype":"BUY",
"exchange":"NSE",
"ordertype":"LIMIT",
"producttype": "BO",
"duration": "DAY",
"price": 10.2,
"triggerprice":10,
"squareoff": 120,
"stoploss": 80,
"quantity": 25
}
orderId=obj.placeOrder(orderparams)
It is failing with the following error:

TypeError Traceback (most recent call last)

---> 27 orderId=obj.placeOrder(orderparams)
28 print("The order id is: {}".format(orderId))
