Receiving Empty in Upstox WebSocket for Options Data

Developer API
1

When subscribing to options data using Upstox WebSocket API, I am receiving empty objects like this:

json

CopyEdit

{ 
  marketFF: { 
    ltpc: {}, 
    marketLevel: {}, 
    optionGreeks: {} 
  } 
}

This issue occurs even after successfully establishing a WebSocket connection and subscribing to valid instrument keys for Nifty
feeds: {
‘NSE_FO|68432’: { fullFeed: [Object], requestMode: ‘full_d5’ },
‘NSE_FO|68435’: { fullFeed: [Object], requestMode: ‘full_d5’ }
},

getting empty at fullFeed

@Upstox can you help me for this

The instrument key NSE_FO|68432 is either invalid or may have expired. Please refer to the instrument JSON file for valid and updated instrument keys: Instrument JSON File.

Thank you!
