Hey @Stefan, not sure if I understand well what you want to do. I’m guessing this is the response from an HTTP request and you want to get jus the patients. If so, check the example below.

{
  "nodes": [
    {
      "parameters": {},
      "name": "Start",
      "type": "n8n-nodes-base.start",
      "typeVersion": 1,
      "position": [
        250,
        300
      ]
    },
    {
      "parameters": {
        "url": "https://mockup-pj5l0yxsjrbr.runkit.sh/",
        "options": {}
      },
      "name": "HTTP Request1",
      "type": "n8n-nodes-base.httpRequest",
      "typeVersion": 1,
      "position": [
        540,
        300
      ]
    },
    {
      "parameters": {
        "functionCode": "const results = []\n\nfor (const item of items) {\n  for (const patien of item.json.Response.patiens) {\n    results.push({\n        json: {\n            patien, \n        }\n     })\n  }\n}\n\nreturn results\n\n\n"
      },
      "name": "Function",
      "type": "n8n-nodes-base.function",
      "typeVersion": 1,
      "position": [
        750,
        300
      ]
    }
  ],
  "connections": {
    "Start": {
      "main": [
        [
          {
            "node": "HTTP Request1",
            "type": "main",
            "index": 0
          }
        ]
      ]
    },
    "HTTP Request1": {
      "main": [
        [
          {
            "node": "Function",
            "type": "main",
            "index": 0
          }
        ]
      ]
    }
  }
}
