Integromat - Dynamically render spec of a collection from an rpc - json

Question

I am trying to dynamically render a spec (Specification) of a collection from an RPC. Can't get it to work. Here I have attached the code of both 'module->mappable parameters' and the 'remote procedure->communication' here.
module -> mappable parameters
[
{
"name": "birdId",
"type": "select",
"label": "Bird Name",
"required": true,
"options": {
"store": "rpc://selectbird",
"nested": [
{
"name": "variables",
"type": "collection",
"label": "Bird Variables",
"spec": [
"rpc://birdVariables"
]
}
]
}
}
]
remote procedure -> communication
{
"url": "/bird/get-variables",
"method": "POST",
"body": {
"birdId": "{{parameters.birdId}}"
},
"headers": {
"Authorization": "Apikey {{connection.apikey}}"
},
"response": {
"iterate":{
"container": "{{body.data}}"
},
"output": {
"name": "{{item.name}}",
"label": "{{item.label}}",
"type": "{{item.type}}"
}
}
}
Thanks in advance.

Just tried the following and it worked. According to Integromat's Docs you can use the wrapper directive for the rpc like so:
{
"url": "/bird/get-variables",
"method": "POST",
"body": {
"birdId": "{{parameters.birdId}}"
},
"headers": {
"Authorization": "Apikey {{connection.apikey}}"
},
"response": {
"iterate":"{{body.data}}",
"output": {
"name": "{{item.name}}",
"label": "{{item.label}}",
"type": "{{item.type}}"
},
"wrapper": [{
"name": "variables",
"type": "collection",
"label": "Bird Variables",
"spec": "{{output}}"
}]
}
}
Your mappable parameters would then look like:
[
{
"name": "birdId",
"type": "select",
"label": "Bird Name",
"required": true,
"options": {
"store": "rpc://selectbird",
"nested": "rpc://birdVariables"
}
}
]

Needing this myself. Pulling in custom fields that have different types but would like them all to show for the user to update customs fields or when creating a contact be able to update them. Not sure if best to have them all show or have a select drop down then let the user use the map for more than one.
Here is my response from a Get for custom fields. Could you show how my code should look. Got little confused as usualy look for add a value in the output and do you need two separate RPC's in integromat? Noticed your store and nested were different.
{
"customFields": [
{
"id": "5sCdYXDx5QBau2m2BxXC",
"name": "Your Experience",
"fieldKey": "contact.your_experience",
"dataType": "LARGE_TEXT",
"position": 0
},
{
"id": "RdrFtK2hIzJLmuwgBtAr",
"name": "Assisted by",
"fieldKey": "contact.assisted_by",
"dataType": "MULTIPLE_OPTIONS",
"position": 0,
"picklistOptions": [
"Tom",
"Jill",
"Rick"
]
},
{
"id": "uyjmfZwo0PCDJKg2uqrt",
"name": "Is contacted",
"fieldKey": "contact.is_contacted",
"dataType": "CHECKBOX",
"position": 0,
"picklistOptions": [
"I would like to be contacted"
]
}
]
}
