Android Kotlin: отсутствует google_app_id. Аналитика Firebase отключена

Question

Я разрабатываю социальную сеть на Android. Данные хранятся в Firebase. Я начинаю с аутентификации. Это работает. И теперь у меня есть модуль чата. Но у меня проблема только при запуске приложения.

У меня есть это сообщение logcat:

2020-04-03 02:20:04.154 23409-23454/? W/FA: Failed to retrieve Firebase Instance Id
2020-04-03 02:20:04.960 23409-23454/? W/FA: Failed to retrieve Firebase Instance Id

Please fix your application to end transactions in progress properly and to close the database when it is no longer needed.

Я даю вам свое приложение build.gradle
