MSFS2020 SimConnect Question: AI Traffic State

Hi,

I'm trying to develop a SimConnect program to monitor AI Traffic.  I'm able to do this successfully for some AI Traffic SimVars (like Airspeed) using SimConnect_AddToDataDefinition, SimConnect_RequestDataOnSimObject, etc.., but I cannot see the AI Traffic State (STATE_ENROUTE_AS_FILED, STATE_WAIT_INIT_CONFIRM, etc.).  The name of this variable is given online as "AI TRAFFIC STATE", but I get "EXCEPTION_NAME_UNRECOGNIZED" when I try to request it.  I wonder have Asobo changed the name of this to something else?

Thanks,

John
