Setting new payload issue

General
1

Hi,

I'm trying to set a new payload through a function when the percentage gets low, so I can send a notification to IFTTT.

Here is what my function contains:

foodlevel = msg.payload

if (foodlevel <= 30) {
    msg.payload.value1 = "Your cat is running low on food";
    return [ msg, null ];
}
else {
    msg.payload = false;
    return [ null, msg ];
}
return msg;

Now, if I set msg.payload.value1 straight in an injection node, it works fine. But not in this function node. Let's say I inject 15 and but a debug node at the end, I only receive the msg.payload value

Any ideas?

Thanks!!

If payload is not an object you cannot add a property .value1

You can set payload to an object with a value1 prop like this...
msg.payload = { value1: "Your cat is running low on food" };

Perfect i'll do it that way then. I was trying to follow the node's instruction:

ifttt out
Publishes msg.payload.value1, 2 and 3 to the
Maker channel in IFTTT in the specified channel.
