Can't get dynamic sample to work

I am building a custom app which is pretty much ready for production, only 1 feature remains and already spend hours and hours on it.

So people can “Watch New Responses” which is a instant webhook.
People connect with their API key and select a survey from the list.
This all works but i need to fetch a real sample for that specific survey after they click “OK” so that the form questions are available for the next app.

I created an RPC (getfeedbacklivesample) like this:
{
“url”: “/forms/123456/sample/”, //{{parameters.survey_id}}
“method”: “GET”,
“response”: {
“limit”: 1,
“output”: “{{body}}”
}
}

This gives the following response:
[
{
“3544”: {
“answer”: 10,
“original_answer”: “”,
“type”: 4,
“qid”: 3544,
“datatype”: 16,
“so”: 0,
“q”: “Hoe waarschijnlijk is het dat u…”
},
“3587”: {
“answer”: “Perfect”,
“original_answer”: “”,
“type”: 8,
“qid”: 3587,
“datatype”: 0,
“so”: 1,
“q”: “Wat kan beter?”
}
}
]

This data should be added to a “Answers” label in the module sample/interface.

In the “Watch New Responses” module interface i have this:

[
{
“name”: “survey_id”,
“type”: “number”,
“label”: “Survey ID”
},
{
“name”: “account_id”,
“type”: “number”,
“label”: “Account ID”
},
{
“name”: “ws”,
“type”: “number”,
“label”: “Workspace”
},
{
“name”: “identifier”,
“type”: “text”,
“label”: “Visitor ID”
},
{
“name”: “page_id”,
“type”: “text”,
“label”: “Page ID”
},
{
“name”: “event_date”,
“type”: “collection”,
“spec”: [
{
“name”: “$date”,
“type”: “collection”,
“spec”: [
{
“name”: “$numberLong”,
“type”: “text”
}
]
}
],
“label”: “Date”
},
{
“name”: “time_reg”,
“type”: “text”,
“label”: “Time”
},
{
“name”: “sentiment”,
“type”: “number”,
“label”: “Sentiment”
},
{
“name”: “cn”,
“type”: “text”,
“label”: “Country”
},
{
“name”: “ref”,
“type”: “text”,
“label”: “Referer”
},
{
“name”: “page”,
“type”: “text”,
“label”: “Page”
},
{
“name”: “os”,
“type”: “number”,
“label”: “OS (ID)”
},
{
“name”: “dev”,
“type”: “number”,
“label”: “Device (ID)”
},
{
“name”: “brow”,
“type”: “number”,
“label”: “Browser (ID)”
},
{
“name”: “width”,
“type”: “number”,
“label”: “Viewport Width (px)”
},
{
“name”: “height”,
“type”: “number”,
“label”: “Viewport Height (px)”
},
{
“DYNAMIC ANSWERS ARRAY SHOULD COME HERE”
},
{
“name”: “id”,
“type”: “text”,
“label”: “ID”
}
]

In the sample tab of that module i tried multiple things like:
“rpc://getfeedbacklivesample”

And: “name” : “answers”, “type”:“array”, “options”: “rpc://getfeedbacklivesample”, etc.
Also tried this in the interface tab but it doesn’t work at all or i see the full internal make rpc link at every interface entered structure.

It all doesn’t work, please help.
