Я создаю чат-бота, который я интегрировал с Dialogflow и Firebase.Как я могу исправить проблему ошибки сеанса (показанную ниже) в Logcat Firebase?Это из-за проблемы в моей Android Studio или моего соединения с Firebase?У меня возникает проблема с надуванием моего представления рециркулятора, которое использует FirebaseRecyclerAdapter для его раздувания.
Регистрация приложения Firebase для подключения к его серверу заняла много времени, поэтому я пропустил шагдумая, что я подключу его через файл google-json.
Поскольку я использую базу данных Firebase UI v5.0.0, мне пришлось изменить метод FirebaseRecyclerAdapter в соответствии с недавним обновлением, приведенным здесь: https://github.com/firebase/FirebaseUI-Android/blob/master/database/README.md

В коде нет ошибок, но logcat, когда я выбираю firebase, показывает эти ошибки:
E/SystemUpdate-Connection: create session error : RESULT_ERROR
E/MiPicks-Connection: create session error : RESULT_ERROR
E/MiPicks-ConnectionRSA: get key exception : com.android.org.bouncycastle.util.encoders.DecoderException: unable to decode base64 string: invalid characters encountered in base64 data
И я тоже получаю RecyclerViewException.Вероятно, ошибки связаны с тем, что RecyclerView не раздувается:
