我正在尝试从现有后端为多个前端导入授权（在本例中为 Android 和 iOS 应用程序；但此错误是从 Android 方面开始的）但是当按照那里的指南进行操作时，我在这一步停止由于错误：
% amplify import auth
Using service: Cognito, provided by: awscloudformation
✔ What type of auth resource do you want to import? · Cognito User Pool only
? Select the User Pool you want to import: …
❯ The selected Cognito User Pool does not have at least 1 Native app client configured. Native app clients are app clients with a client secret.
dev-user-pool (us-east-1_.........)
因此，只有在调用 Amplify.Auth.signIn 后我得到此异常后，我才创建一个带有 App 客户端密码的 App 客户端以继续：
Sign in failed
com.amazonaws.services.cognitoidentityprovider.model.NotAuthorizedException: Unable to verify secret hash for client .......................... (Service: AmazonCognitoIdentityProvider; Status Code: 400; Error Code: NotAuthorizedException; Request ID: ........-....-....-....-............)

我发现的围绕此异常的所有资源似乎都解释了相反的情况，但如果我不创建应用程序客户端密码，我就无法按照说明继续？
