Array sending does not work - code help needed

Hello There,

I am developing a custom app for bundeling, which is working well except of one issue: in the API documentation of Bundeling (which I create the app for) I have to sent some informations in an extra array (I guess) and this does not work, I always receive an error “wrong formatting”

This is my communication code:

{
// Request to API endpoint with parameter “id” defined in Mappable parameters.
“url”: “/news/”, // Relative to base URL
“method”: “POST”,
“headers”: {}, // Additional HTTP headers
“qs”: {}, // Query string
“body”: “{{parameters}}”,
“response”: {
“output”: “{{body}}” // Returns no output bundle as no API output is expected.
}
}

And this is my mappable parameter:
{
“name”: “labels”,
“type”: “select”,
“options”: “rpc://newscats”,
“label”: “Labels”
}

No the problem is: the correct value comes with the RPC but if I add a category and try to send is, I receive a [400] One or more fields contain invalid types -Error.

I guess it is because of the API because in “Labels” they are awaiting another format, here is their example API Call:

{
“author_uuid”: “d7743aaf53224e279853c7d0c1dbfb3a”,
“title”: “Welcome to Bundeling”,
“content”: “Bundeling would like to welcome…”,
“category_uuid”: “8e09c4749b234633a7319148aac8cb81”,
“event_uuid”: “d669b048d2084892b5a5232b78923227”,
“sponsor_uuid”: “48b99d307f8746a8b126f76be5d1153e”,
“link”: “www.ecom.nl”,
“social_sharing”: true,

“comments_enabled”: true,
“draft”: false,
“publicationdate”: “2024-03-22T00:00:00+0100”,
“external_reference”: “123908”,
“labels”: [

],
“actions”: {
“pushbroadcast_1_1”: {
“enabled”: true
}
}
}

Anyone has an idea how I am able to solve this issue?

Many thanks in advance
