MFS2020 : Aircraft management from node-simconnect

[Oru-Bus]

Hello, I'd like to know if it's possible to manage the aircraft by sending it data, and if so, how? For example, we can find out the altitude of the autopilot by doing :

handle.addToDataDefinition(
            ALTITUDE_DATA,
            AUTOPILOT ALTITUDE LOCK VAR,
            feet',
            SimConnectDataType.FLOAT64,
            0.0,
            SimConnectConstants.UNUSED
 ) ;

handle.requestDataOnSimObject(
            REQUEST_ID_ALTITUDE_DATA,
            ALTITUDE_DATA,
            SimConnectConstants.OBJECT_ID_USER,
            SimConnectPeriod.SECOND,
            0,
            0,
            0,
            0
) ;
....

But is it possible to increase the autopilot altitude from node-simconnect?

For example, I tried :

const altitudeIncrement = 1000 ;

handle.transmitClientEvent(
    SimConnectConstants.EVENT_ID_AP_ALT_VAR_INC,
    altitudeIncrement,
    0, // Additional parameter (0 by default)
    SimConnectConstants.OBJECT_ID_USER,
    SimConnectConstants.EVENT_FLAG_GROUPID_IS_PRIORITY
 ) ;

But here's the error I got:

Error: TypeError: Illegal value: undefined (not an integer)
