Как исправить ошибку конструктора класса для получения данных из Firebase?

Мне необходимо принимать данные сервера и затем они должны отправляться в MainActivity, плохо разбираюсь с конструкторами и классами, но код такой:

class Houses(_costV: String,  _locationV: String, _roomsV: String, _squareV: String,_image: String, _infoV: String,_pid: String,  _date: String,_time: String) {
private var costV: String
private var locationV: String
private var roomsV: String
private var squareV: String
private var image: String
private var infoV: String
private var pid: String
private var date: String
private var time: String
init {
    costV=_costV
    locationV=_locationV
    roomsV=_roomsV
    squareV=_squareV
    image=_image
    infoV=_infoV
    pid=_pid
    date=_date
    time=_time
}




fun getCostV(): String {
    return costV
}

fun setCostV(costV: String) {
    this.costV = costV
}

fun getLocationV(): String {
    return locationV
}

fun setLocationV(locationV: String) {
    this.locationV = locationV
}

fun getRoomsV(): String {
    return roomsV
}

fun setRoomsV(roomsV: String) {
    this.roomsV = roomsV
}

fun getSquareV(): String {
    return squareV
}

fun setSquareV(squareV: String) {
    this.squareV = squareV
}

fun getImage(): String {
    return image
}

fun setImage(image: String?) {
    this.image = image!!
}

fun getInfoV(): String {
    return infoV
}

fun setInfoV(infoV: String) {
    this.infoV = infoV
}

fun getPut(): String {
    return pid
}

fun setPut(pid: String) {
    this.pid = pid
}

fun getDate(): String {
    return date
}

fun setDate(date: String) {
    this.date = date
}

fun getTime(): String {
    return time
}

fun setTime(date: String) {
    this.time = date
}

}

Соответственно у меня вылетатет ошибка конструктора:

com.google.firebase.database.DatabaseException: Class ru.homebuy.neito.Model.Houses does not define a no-argument constructor. If you are using ProGuard, make sure these constructors are not stripped.
