Duplicate OrderID Issue in NinjaTrader integration with Interactive Broker

[vivekniwas]

See the trace file extract below. Why am I getting this error.

As per NinjaTrader 8 documentation internal OrderID is sent to the API by NinjaTrader and when Broker has the OrderID , internalOrderID is replaced by Broker supplied OrderID.
As per Interactive Brokers API support forums, it expects unique OrderID or no OrderID in the API call or else it returns Duplicate OrderID error.

Does NinjaTrader not generate a GUID e.g.

'1bce9181776e4fb0b538b157fd3f2298'

in the below log as OrderID , if so why I am getting this error, what can I do so this error does not occur.
