Modify CO Error

Hi,

I am able to execute a buy CO, however, when I want to modify my Stoploss i.e. for sell-side, I am getting error.

My line is as below:

Unhandled Error

kite.modify_order(variety="CO",order_id=orderid, parent_order_id=parent_order_id, trigger_price=newslprice, order_type="LIMIT")
