How to add new Items to the array by using jolt spec file in JSON data

Question

I'm facing issue while adding new Items to an Array. I want to add new Items in address array. any help would be appreciate. Thanks in advance:

This is my code:

input.json

{
  "lines": [
    {
      "movement": {
        "source": {
          "node": "Org_Node",
          "address": {
            "addressLine1": "abc",
            "addressLine2": "def",
            "addressLine3": "eg",
            "addressLine4": "abc123"
          },
          "recipient": {
            "firstName": "Ravi",
            "middleName": "",
            "lastName": "krishna"
          },
          "contactInformation": {
            "mobileNo": "9687568965"
          }
        }
      }
    }
  ]
}

In output I want to add city& state: Expected output is:

{
  "address" : {
    "address1" : "abc",
    "address2" : "def",
    "address3" : "eg",
    "address4" : "abc123",
    "city":"ATP",
    "state":"AP"
  },
  "recipient" : {
    "firstName" : "Ravi",
    "middleName" : "",
    "lastName" : "krishna"
  },
  "contactInformation" : {
    "mobileNo" : "5036412733"
  }
}

I wrote following spec file to get my desired output,Please let me know where i have to modify I'm new to JOLT. spec.json file:

    [{
  "operation": "shift",
  "spec": {
    "lines": {
      "*": {
        "movement": {
          "source": {
            "address": {
              "addressLine*": "[#5].&1.address&(0,1)",
              "*": "[#5].&1.&"
            },
            "recipient": {
              "*": "[#5].&1.&"
            },
            "contactInformation": {
              "*": "[#5].&1.&"
            }
          }
        }
      }
    }
  }
}]

Spec

[
  {
    "operation": "shift",
    "spec": {
      "lines": {
        "*": {
          "movement": {
            "source": {
              // keeping the lines array
              // just keep the follow 3 fields
              "address|recipient|contactInformation": "lines[&3].&"
            }
          }
        }
      }
    }
  },
  {
    "operation": "default",
    "spec": {
      // default has a different syntax than shift.
      // You have to tell Default that lines is an array
      //  so that it can step into it correctly.
      "lines[]": {
        "*": {
          "address": {
            // apply cit and state defaults
            // not this is not in any way data driven
            // it will add these city and state defaults to everythhing
            // If you need it to be data driven, you have to deal with
            //  that before or after Jolt
            "city": "ATP",
            "state": "AP"
          }
        }
      }
    }
  }
