Cannot schedule Orchestrations Version 3 (JDE 9.2.3.3)

Hi experts,

I am trying to schedule a version 3 orchestration on 9.2.3.3 (orchestrator studio 7.2.0.0), but it does not work. It works with version 2 orchestrations, but not version 3.

I started everything correctly using:

"../v2/scheduler/startScheduler"

and

"../v2/scheduler/start"

if I ping scheduler, using "../v2/scheduler/pingScheduler" I receive the correct answer:

{

  "schedulerRunning": ""http://.."

}

Looking to the monitor, only version 2 orchestrations are running and no version 3.

Everyhing is shared and I tried with a "standard" schedule and also with a schedule created by me.

When I use command "../v2/scheduler/list" I see this message:

"executionReturnedException": {

            "status": "ERROR",

           "message": "Only Version 2 orchestrations can be called using the Version 2 URL.",
