Невозможно записать данные в базу данных Firebase через Unity

Так что недавно у меня возникли проблемы с попыткой записи / чтения данных в Firebase через Unity. У меня был опыт работы с Firebase на Java (в Android Studio), и в настоящее время я узнаю, как использовать его в Unity на C#.

Раньше у меня была ошибка, когда я не мог получить рукопожатие с базой данных firebase, и это решил, что решил мою проблему, что привело меня к этой ошибке, которую я получаю. Так что сейчас я использую Единство 2018.2.10f1 и Firebase SDK 5.3.0 и быстрый старт от Github. Ошибка, которую я получаю, это

EntryPointNotFoundException: SWIGRegisterExceptionCallbacks_DatabaseInternal

Это происходит при попытке записать данные в базу данных firebase. А вот мои настройки правил в базе данных:

{
  "rules": {
    ".read": true,
    ".write": true
  }
}
