I have tge following error

2024-08-09 11:28:36:167|3|4|Error in realtime market data handling: System.NullReferenceException: Object reference not set to an instance of an object.
at NinjaTrader.NinjaScript.StrategyBase.Process(Objec t sender, ExecutionEventArgs executionUpdate)
at System.EventHandler`1.Invoke(Object sender, TEventArgs e)
at NinjaTrader.Cbi.Account.RaiseExecutionUpdate(Execu tionEventArgs e)

at NinjaTrader.Cbi.Instrument.<>c__DisplayClass153_0. <OnRealtimeDataTimerElapsed>g__Action|1(Subscrib ed Thread[] threads, Int32 i, RealtimeEvents evts)

I have studied my OnExecutonUpdate quite hard and can't seem to find what object instance is missing - can anyone point me in the right direction?
I should add this happens sporadically - so 8/10 code runs fine.

No I didn't do this - the platform said it had an issue posting ( ie to my mind it did not work) - so I re posted.
You can tell by the time stamps FYI.
