リモート設定を同期

 private fun initRemoteConfig(){
    val configSettings = remoteConfigSettings {
        minimumFetchIntervalInSeconds = 3600//3
    }
    remoteConfig.setConfigSettingsAsync(configSettings)
    remoteConfig.setDefaultsAsync(R.xml.remote_config_defaults)
    remoteConfig.fetchAndActivate()
}

Firebase configのローカルコピーがあります。すべてが正常に動作しています。コンソールにエラーが表示されるだけです。

私は同じ問題を抱えています。幸い、すでにパイプラインに修正があります： https://github.com/firebase/firebase-Android-sdk/pull/1209 ...残念ながら、まだ開いています。 2月6日以降：-/

編集：このエラーは問題ではないことを認識しました。リモート設定は引き続き機能します
