How to Skip attribute or key ( eg SSN, password - sensitive )while transforming the object using mapObject

Payload:

[
  {
    "personal_information": {
      "first_name": "Emiliano",
      "middle_name": "Romoaldo",
      "last_name": "Lesende",
      "ssn": "001-08-84382"
    },
    "login_information": {
      "username": "3miliano",
      "password": "mypassword1234"
    }
  },
  {
    "personal_information": {
      "first_name": "Mariano",
      "middle_name": "Toribio",
      "last_name": "de Achaval",
      "ssn": "002-05-34738"
    },
    "login_information": {
      "username": "machaval",
      "password": "mypassword4321"
    }
  }
]

Here I have to remove ssn, password key from.

write now I have personal_information, login_information but i hv more attribute on same level

looking for dynamic way : except personal_information, login_information other attributes doesnt have sensitive information.

I have written below dataweave expression but its giving error. Can someone explain what is the error and solution

 MY code:

%dw 2.0
output application/json
// I have to remove sesitive fields like ssn, password from payload
 
---
payload map (value, key)->{
  (value mapObject(obj, objKey, index)->
   objKey match {
 
      case str if( objKey as String == "personal_information" ) -> ( obj- "ssn")
      case str if( objKey as String == "personal_information" ) -> ( obj- "password")
      else -> obj
    }
 
}

unble to convert xml to json array in dataweave 2.0

output :

"employees":{

"employee":{

"name" : "abc"

},

"employee":{

"name" : "xyz"

}

}

expected output :

"employees":{

"employee" : [

{ "name" : "abc" },

{ "name" : "xyz" }

]

dataweave script :

%dw 2.0

output application/json

---

Hello,

I have a question: if I book an exam A using a voucher, but then I have to cancel the exam and would like to book an exam B using that voucher, can I do it? Or can I no longer use the voucher even if I canceled exam A?

Thanks.
