JSON Path doesn't work ?

Hello, I guess it's a very dumb question but what do I missing ??

I have a cloud function returning this output (as seen in the consol of my browser) :

{
    "result": [
        {
            "brand": "Car1",
            "model": "ModelA",
            "price": "80000",
            "cardID": "abc123",
            "collectionParent": "cars"
        },
        {
            "name": "Artwork1",
            "price": "35000 USD",
            "autor": "Artist1",
            "cardID": "def456",
            "collectionParent": "arts"
        },
        {
            "model": "Aircraft1",
            "price": "20000000",
            "range": "3000 NM",
            "cardID": "ghi789",
            "collectionParent": "airs"
        }
    ]
}

the return of my funciton is clearly :

return finalDocs;

So the "result" comes from the cloud funciton i guess, not in my code.

And in my flutterflow, i put this output in an app state => list json.
and the json path is just "$" :

I guess since there is only result that goes directly in ? maybe but this is working.

Then I wanted to upgrade my function (just want to add pagination) so i need 2 output

so the return of my function is :

return {
  documents: finalDocs, // This will contain the actual list of documents
  paginationData: {     // Placeholder data for pagination testing
    lastDoc: {
      id: "randomDocID123",
      timestamp: Date.now() // Random data, e.g., a timestamp for this example
    }
  }
};

and in the console the output is something like that :

{
    "result": {
        "documents": [
            {
                "brand": "Car1",
                "model": "ModelA",
                "price": "70000",
                "cardID": "abc123",
                "collectionParent": "cars"
            },
            {
                "model": "Aircraft1",
                "price": "23000000",
                "cardID": "def456",
                "collectionParent": "airs"
            },
            {
                "capacity": 12,
                "range": "2400 NM",
                "cardID": "ghi789",
                "collectionParent": "airs"
            }
        ],
        "paginationData": {
            "lastDoc": {
                "id": "randomDocID123",
                "timestamp": 1731576970895
            }
        }
    }
}

So now in the json path i tried :

$.documents

$.documents[*]

$.result.documents

$.result.documents[*]

with my first output i also tried $.result or $.result[*] nothing is working except the "$" alone....

When i try all those json path in https://jsonpath.com many of them are working... but in flutterflow, it's always empty 😞

Do you have any idea ? do i miss something ? is it because my app state is a list of json ? but if I take only $.result.documents the output is a list of json... I think... right ?
