Fix JOLT config to get missed value

Source JSON:

[
  {
    "updated": "2025-04-07T12:59:07+03:00",
    "author": {
      "name": "Adriver::RestAPI::Statistics"
    },
    "content": {
      "type": "text/xml",
      "statUniqueObject": {
        "object": {
          "id": 810069,
          "type": "AD"
        },
        "stat": {
          "item": [
            {
              "exp": 34725,
              "click": 789,
              "reach": 331399,
              "date": "2025-04-05"
            },
            {
              "exp": 32090,
              "click": 747,
              "reach": 344560,
              "date": "2025-04-06"
            }
          ]
        }
      }
    }
  }
]

Idea is - grab stat.item array an add to each element of array id from object. My JOLT config:

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "content": {
          "statUniqueObject": {
            "object": {
              "id": "[&4].id"
            },
            "stat": {
              "item": {
                "*": {
                  "*": "[&1].&"
                }
              }
            }
          }
        }
      }
    }
  }
]

Result:

[
  {
    "id": 810069,
    "exp": 34725,
    "click": 789,
    "reach": 331399,
    "date": "2025-04-05"
  },
  {
     //no id here
    "exp": 32090,
    "click": 747,
    "reach": 344560,
    "date": "2025-04-06"
  }
]

I expect to get field id for all elements in item array, but it goes only for 1st element. How to fix it?

You can grab it within the objects of the array by picking after going 3 levels up such as

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "content": {
          "statUniqueObject": {
            "stat": {
              "item": {
                "*": {
                  "@3,object.id": "[&1].id",
                  "*": "[&1].&"
                }
              }
            }
          }
        }
      }
    }
  }
]
