piyushk921 in Python client
I am running my script for my friend and in between i got this error "ERROR:websocket:error from callback >: Invalid session".

May I know the reason behind it and how to rectify this ?

    Hi @piyushk921,
    This is error message is from order_place method, it will be called when a session is expired.
    This can happen when a user logged into to any of our platforms like PI or NEST. I would suggest using Kite for monitoring purpose and if you log out of any platform then you are logged out everywhere.
