关于 android：使用 Facebook 登录 Firebase 时出现错误 100

Error 100 while logging with Facebook into Firebase

我正在尝试使用 facebook 登录到 firebase。 Facebook 登录有效，但 firebase 抛出错误。顺便说一句，Google 登录效果很好(我删除了 GSI 代码以使其更短)，所以我非常怀疑问题出在 Firebase 上。
这是日志

我在这个错误中搜索了大约 3 个小时，但到处都只找到了一个解决方案 - 在 Facebook 控制台设置中关闭"秘密嵌入客户端"。这根本没有效果。

P.S.：使用 gradle 添加的 Facebook SDK，可能是导致问题的原因吗？ build.gradle 的一部分：

1 2	compile 'com.google.firebase:firebase-auth:9.4.0' compile 'com.facebook.android:facebook-android-sdk:[4,5)'
