Clarus mqtt problem

[lokomotionn]

Hello, I have a problem with sending mqtt from node red to MQTT433gateway protocol clarus.
The subject I send to is rf434 / send / clarus_switch
or rf434 / send / rev2_switch
the code received from the remote control is
"rf signal received: {" id ":" A3 "," unit ": 4," state ":" on "} with protocol clarus_switch deviceID = A3"
and tries to send with such syntax {"id": "A3", "unit": 4, "state": "on"} what am I doing wrong? What is the correct syntax for MQTT433gateway to pick up mqtt from node red?
I tried in many ways but I always get some error : "transmitting failed: message is invalid" , "message is not a proper json object" or insufficient number of arguments, what is the correct syntax ?
When i send
"id": "A3",
"unit": 4,
"state": "ON"
it returns me such an error: pilight(3): clarus_switch: insufficient number of arguments
transmitting failed: message is invalid

Thank your for trying MQTT433gateway!

Unfortunately, the syntax for transmitting differs from receiving, due to the implementation in pilight.

If you receive: {"id": "A3", "unit": 4, "state": "on"}

Please try:
on: {"id": "A3", "unit": 4, "on": 1}
off: {"id": "A3", "unit": 4, "off": 1}
