Permission Denied on n8n integration

Hello!

I want to integrate a pipefy pipe to n8n, but i'm getting a problem.

On my n8n flow I have a http request to get the pipefy data, but my ouput in this part returns this:
 

1[
2  {
3    "data": {
4      "card": null
5    },
6    "errors": [
7      {
8        "message": "Permission denied",
9        "locations": [
10          {
11            "line": 1,
12            "column": 9
13          }
14        ],
15        "path": [
16          "card"
17        ],
18        "extensions": {
19          "code": "PERMISSION_DENIED",
20          "correlation_id": "955423756e7991db-FRA"
21        }
22      }
23    ]
24  }
25]

Does anyone knows how to solve this?
I'm just trying to get the card id while moving a card.
The problem its not a permission, because I have access to the pipe and the card.
And the first webhook on my n8n flow even gets the data, so I think the problem would be another thing.
