Need help with MarketDataFeedV3 first tick onwards

Developer API
1

I am trying code which will get any of the available mode - “LTPC”: “ltpc”, “FULL”: “full”, “OPTION”: “option_greeks”, “D30”: "full_d3

The problem is that I do not get the second tick and onwards. I get the first response like this

"
