I am trying to connect to websocket (500 symbols)… I’m seeing that getting Error call back with message Error :‘ft’

But Token Acknowledgement status :{‘t’: ‘tk’, ‘pp’: ‘2’, ‘ml’: ‘1’, ‘e’: ‘NSE’, ‘tk’: ‘19061’, ‘ts’: ‘MANAPPURAM-EQ’, ‘ls’: ‘1’, ‘ti’: ‘0.05’, ‘c’: ‘125.80’, ‘lp’: ‘125.80’, ‘pc’: ‘1.62’, ‘o’: ‘123.70’, ‘h’: ‘126.70’, ‘l’: ‘121.55’, ‘toi’: ‘125796000’, ‘ft’: ‘1687775376’, ‘v’: ‘8484591’, ‘bp1’: ‘125.80’, ‘sp1’: ‘0.00’, ‘bq1’: ‘48624’, ‘sq1’: ‘0’, ‘ap’: ‘124.39’} does have ‘ft’ Any thoughts ? Pointers ?
