Hi,

I am trying to iterate through a list of users using a For loop, but am receiving duplicate values when pushed to json.

The ID for Username 7 in my example is copied to all values, even though the username shows up correctly in the JSON.

Why is it pushing idForUser7 to all of them here?

{
  "username 1" : {
    "id" : "idForUser7"
  },
  "username 2" : {
    "id" : "idForUser7"
  },
  "username 3" : {
    "id" : "idForUser7"
  },
  "username 4" : {
    "id" : "idForUser7"
  },
  "username 5" : {
    "id" : "idForUser7"
  },
  "username 6" : {
    "id" : "idForUser7"
  },
  "username 7" : {
    "id" : "idForUser7"
  }
}

As a side note, the reason I am going with this approach is to avoid the attributes/type/url when pushing an SObject Map to json.

"attributes" : {
"type" : "User",
"url" : "/services/data/v49.0/sobjects/User/0053t000007t21nAAA"
},

public static string getActiveUsers() {
 		
        Map<string, Map<String, String>> userActiveMap = new Map<string, Map<String, String>>();
        Map<String, String> userActiveMapValue = new Map<String, String>();
        
        try{
            
			for(List<User> activeUsersList : [ select id,username,LastLoginDate,ProfileId from User where IsActive = True]) {
                
                for (User u : activeUsersList) {
                    
                    userActiveMapValue.clear();
                    
                    userActiveMapValue.put('id', string.valueof(u.id));
                    
                    userActiveMap.put(  string.valueof(u.Username) , userActiveMapValue);
                     
                }
                
            }
        
        	
            
         } catch(DmlException e) {
            	System.debug('An unexpected error has occurred: ' + e.getMessage());
         }
            
        return json.serialize(userActiveMap);
        
    }
