Android上的Cognito UserPool登录超时

Question

I'm trying to use Cognito for authenticating users in my Android app. I created a UserPool (with mfa disabled) and an app. Signup and confirmation works fine from the app, so I would assume the network connection itself is OK, but the signin fails.

This is the code I'm using for the signin:

AuthenticationHandler authenticationHandler = new AuthenticationHandler() {

    @Override
    public void onSuccess(CognitoUserSession cus, CognitoDevice cd) {
        // do something
    }

    @Override
    public void getAuthenticationDetails(AuthenticationContinuation authenticationContinuation, String userId) {
        AuthenticationDetails authenticationDetails = new AuthenticationDetails(p.getUserName(), p.getPassword(), null);
        authenticationContinuation.setAuthenticationDetails(authenticationDetails);
        authenticationContinuation.continueTask();
    }

    @Override
    public void getMFACode(MultiFactorAuthenticationContinuation multiFactorAuthenticationContinuation) {

    }

    @Override
    public void onFailure(Exception exception) {
        LOG.log(Level.SEVERE, "Failure of Login", exception);
    }

    @Override
    public void authenticationChallenge(ChallengeContinuation cc) {

    }
};
user = userPool.getCurrentUser();
user.getSessionInBackground(authenticationHandler);

This fails after a couple of seconds with the Exception below. The getAuthenticationMethod is called, the other methods (getMFACode and authenticationChallenge aren't, as I would have expected):

Used versions of aws APIs:

    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-android-sdk-core</artifactId>
        <version>2.11.0</version>
    </dependency>
    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-android-sdk-cognitoidentityprovider</artifactId>
        <version>2.11.0</version>
    </dependency>

What could be the reason for this?

Answer 1

I solved the issue by testing with the JavaScript API. Authentication also failed, but the error object gave me a detailed message why the issue occurred. The problem was a lambda triggered post-authentication. This lambda failed. After removing the lambda in question, authentication worked.
