Dynamically trying to update a field in an object using dataweave, how to achieve the same? - mule

Question

The use case is : we'll be having translations stored in an object in a variable in the dataweave, we have to dynamically assign those translations in the "calingaKey" value, I tried doing something below, but it isn't working.
Input
{
"editable": true,
"sections": [
{
"title": "Identification",
"calingaKey": "",
"content": [
{
"name": "Classification",
"text": "Product",
"url": "",
"info": ""
},
{
"name": "Product Number",
"text": "####1234",
"url": "",
"info": ""
}
]
},
{
"title": "Position and Contact",
"calingaKey": "",
"content": [
{
"name": "Manufacturer",
"text": "Value of Manufacturer",
"url": "",
"info": ""
},
{
"name": "Hardware Version",
"text": "####1234",
"url": "",
"info": ""
}
]
}
]
}
Dataweave
%dw 2.0
import * from dw::util::Values
output application/json
var calinga = {
"title": "titel",
"Position and contact": "Lage und Kontakt"
}
---
payload.sections map (item,index)->(item mapObject ((value, key, index) -> {'$(key)' : value} update field("calingaKey") with calinga.'$(key)' ))
"calinga.'$(key)'" doesn't seem to work for some reason, and gives me null, any issue with my code?
Expected Output
[
{
"title": "Identification",
"calingaKey": "titel",
"content": [
{
"name": "Classification",
"text": "Product",
"url": "",
"info": ""
},
{
"name": "Product Number",
"text": "####1234",
"url": "",
"info": ""
}
]
},
{
"title": "Position and Contact",
"calingaKey": "titel",
"content": [
{
"name": "Manufacturer",
"text": "Value of Manufacturer",
"url": "",
"info": ""
},
{
"name": "Hardware Version",
"text": "####1234",
"url": "",
"info": ""
}
]
}
]

var calinga = {
"title": "titel1",
"calingaKey": "titel1",
"Position and contact": "Lage und Kontakt"
}

payload.sections map (item,index)->(item mapObject ((value, key, index) -> {'$(key)' : value} update field("calingaKey") with calinga[key]
))
