我们正在尝试在 Android 上配置 AWS Amplify 身份验证 (Cognito)，但是当我们尝试使用有效的用户名和密码登录用户时，会调用 onResult 回调，其 signInState 等于 SignInState.DONE，但是当我们尝试获取令牌（同步或异步），引发异常：“getTokens 不支持在注销时检索令牌”。

查看日志，似乎引发了未处理的异常并被忽略（因为登录状态为 DONE）：

我的配置：

build.gradle（应用程序）

implementation "com.amazonaws:aws-android-sdk-mobile-client:2.13.4"
implementation "com.amazonaws:aws-android-sdk-auth-userpools:2.13.4"

MainApplication.kt（扩展应用程序）

AWSMobileClient.getInstance().initialize(applicationContext, object : Callback<UserStateDetails> {
    override fun onError(e: Exception?) {
        Timber.e(e, "An error occurred while tried to init the AWSMobileClient")
    }
    override fun onResult(result: UserStateDetails?) {
        Timber.d("Successfully started …
