Set change-node Payloadpath to msg.payload.+global

[Dom19882]

Thanks. I will read about it

I have read about the hasownproperty thing, but my knowledge was not deep enough to understand it complety.

I tried your modified version and even added after getting error messages nevertheless my part to:
const key = global.get("ZBB_BMotion");
if (msg.payload.ZbReceived.hasOwnProperty(key) !== null && msg.payload !== '') {
msg.payload = msg.payload.ZbReceived[key];
return msg;
}

But that doesnt solved the error messages also.

If you want it the other way try

  $lookup(payload.ZbReceived, $globalContext("test"))

If you take the exact function i posted it should never get to the part that creates the error at least if your input messages always have the msg.payload.ZBreceived object.

@E1cid

$lookup(payload.ZbReceived, $globalContext("test"))

Thats the one, nice now on to add the other tests as below

[Dom19882]

Yes, i understand. i found out there are more messages send like ...ZbBind, ZBStatus. Is there a way to filter that out?

[JGKK]

Yes add the other conditions to the if statement:

const key = global.get("BathroomMotion");
if (typeof msg.payload === "object" && msg.payload.hasOwnProperty("ZbReceived") && msg.payload.ZbReceived.hasOwnProperty(key)) {
    msg.payload = msg.payload.ZbReceived[key];
    return msg;
} else {
    return null;
}

This checks if the payload is an object, has the ZbReceived property and the right key
