For some reason cant deserialize object from Firebase response

I hope this helps you . The deserializer that comes with the Realtime Database (and also Cloud Firestore) Android SDKs requires that the class you pass to it look like a JavaBean type object. This means that it must have a default no-arg constuructor, as you can tell from the error message, and also setter methods that map to each database field.
Kotlin data classes don't provide a default no-arg constructor in order to ensure that all of its fields have an initial value. You can tell Kotlin that it's OK for all of the fields not to have an initial value by giving null or some other value as a default value:
data class GameUnit (
    var background: String = null,
    var description: String = null,
    var tag: String = null,
    var title: String = null,
    var type: String = null
)

Deserialize response from firebase

wish helps you I am using c# interacting with Firebase via the provided REST api. , Here you go (a bit ugly):
public class Item
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public string Value { get; set; }
}
dynamic data = JsonConvert.DeserializeObject<dynamic>(jsonString);
var list = new List<Item>();
foreach (var itemDynamic in data)
{
    list.Add(JsonConvert.DeserializeObject<Item>(((JProperty)itemDynamic).Value.ToString()));
}
dynamic data = JsonConvert.DeserializeObject<dynamic>(jsonString);
var shorter = ((IDictionary<string, JToken>)data).Select(k => 
    JsonConvert.DeserializeObject<Item>(k.Value.ToString())).ToList();

Deserialize response in object C#

like below fixes the issue You are not telling the serialiser what the default namespace is.
Try this:
var stream = new StringReader(dd);
XmlSerializer s = new XmlSerializer(typeof(RunQueryReply), "http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema");
var a = (RunQueryReply) s.Deserialize(stream);

Deserialize Json Response to Object

I wish this helpful for you The response that's being returned from the server here is the JSON representation of a string, which is itself the JSON representation of the object you're expecting. The server is first encoding the object as JSON and then encoding that serialised JSON string as JSON once again.
You've already confirmed in the comments that the solution to this is to fix the server to encode the data only once, so I've written this answer out here for completeness.

Is it possible to serialize and deserialize an object that contain an object as a variable in Firebase?

I wish this help you The Firebase database serializes/deserializes any public fields, and public properties that follow JavaBean naming conventions for getters and setters. Since the classes you show contain neither of those, they will not read or write any data.
If you mark the fields as public or add public getters/setters, then writing an instance of the Profile class will generate this JSON:
"userID": {
  "tenant": {
    "name": "the name",
    "room": {
      "town": "the town",
      "size": 42
    }
  }
}
