I am getting the below error after on_connect is executed: "Connection error: 0 - Error parsing instrument tokens."
below are the lines in the on_connect procedure: ws.subscribe(instrument_token) ws.set_mode(ws.MODE_LTP, instrument_token)
I have used variable instrument_token to store nifty 18 sep future through a congif.ini file which has the following last line: instrument_token = [10991874]
This was working fine till yesterday. Let me know if anyone faced similar issue.
Make sure, you are passing instrument tokens as numbers not as string.
