i m Facing this error Continously from last few days
some times it stop the websocket-ltp
i have to resubscribe than it starts
i m subcribing 25 symbols of FNO - every 5 mins sometimes 20 mins when movement in Spot_Price
what i do is --- i unsubcribe all which were subcribe already and than resubcribe all new List Gap between unsub-resub is 0.2 seconds
but sometimes when this key error comes it stop the LTP
my symbols data is all correct rechecked all symbol - as - it works when i resubcribe after i see the error with same list of symbols
how to fix this issues ? or is it from API backend
