you could convert the object to string (pass it through a JSON node) then pass it through the RBE then pass it once more through a JSON node to convert it back to an Object.

which function ?

:point_down:

Not sure how to say it any clearer. Perhaps my 2nd best explanation will help :wink:

Pass the msg with the payload object through a JSON node (converts it to string) then through the RBE then back through the JSON node to convert it back to an object.

Maybe I'm too newbie :slight_smile:
I thinking about this and it's work with RBE (Apply mode separately for each msg.topic)

for (let x in obj) {
    console.log(x + ": " + obj[x])
    node.send({
        "payload": {
            'opis': x,
            'value': obj[x]
        },
        'topic': x
    });
}
