Unknown request 'unsubscribe'

Hello!

I am trying to unsubscribe after got unpublished event. But getting error:

[ERR] [plugins/janus_videoroom.c:janus_videoroom_handler:10118] Unknown request 'unsubscribe'

My JSON payload:

{
  "janus": "message",
  "session_id": 2346407158877432,
  "handle_id": 8707969878415203,
  "transaction": "73ab3a32cb2749b7a255bbcadb0cb42d",
  "body": {
    "request": "unsubscribe",
    "room": 1234,
    "streams": [
      {
        "feed": 3137530495049616
      }
    ]
  }
}

Janus version: 1104 (1.1.4)

Can you help, please?
Thanks in advance!

I’ve figured, that I sent message to the wrong handle. (Sent to publisher handle instead of subscriber). Though, I got Sender = publisher handle from unpublished event. Is that normal behavior?

Also have a question, after successful update of offer, should be onTrack event triggered? Because I didn’t get onTrack trigger after this mesage:

      }
   }
