Translating payload not showing in text box dashboard

General
1

Trying to monitor my gardena lawnmower, I have a payload (msg.payload[0].devices[0].services[0].activity.value) with activity text, I want to translate and show in text field but it will not show.
It gets translated in my debug node but same output not showing up in text box.

in textbox format field: {{msg.payload.aktivitet}}

in debug payload: msg.payload.aktivitet

Here is an example with injected text, function to translate and output to textbox and debug node:

msg.payload is an array [0].
you can not add an object property to the payload if it is an array.
You would first need to turn msg.payload into an object msg.payload = {}

p.s here is a alternative way rather than all the if statements, you can create a lookup object.

let activity = msg.payload[0].devices[0].services[0].activity.value;
//create lookup object
const translate = {
    "PAUSED": "Sat pĂĄ pause",
    "OK_CUTTING": "Klipper græs (auto)"
    //add more translations here
}
if (Object.keys(translate).includes(activity)){
    msg.payload =  {aktivitet: translate[activity]}; // if activity, translate and make payload an object
}else {
    msg = null; // return null if no activity in lookup
}
return msg;
