While trying to post a sell order for options I got the following error:
{"message":"Failed to get symbol details","errorcode":"AB1018","status":false,"data":null}

While placing the order my python code has correctly identified the strike prices from the complete data dump.
{'token': '44002', 'symbol': 'BANKNIFTY12MAY2133100PE', 'name': 'BANKNIFTY', 'expiry': '12MAY2021', 'strike': '3310000.000000', 'lotsize': '25', 'instrumenttype': 'OPTIDX', 'exch_seg': 'NFO', 'tick_size': '5.000000'}

I tried to debug this issue but not yet successful.
Can anyone help?
