Problema de inicio de sesión de AWS: no se pudieron federar los tokens durante el inicio de sesión java.lang.RuntimeException: Error al federar el token.- Android

Question

Después de cambiar la identificación del grupo de usuarios en amplifyconfiguration.json Para el grupo de usuarios existente, puedo registrarme correctamente, pero al iniciar sesión recibo este error.

para iniciar sesión estoy usando Amplify.Auth.signIn ("*** ", " ", resultado -> {Log.i ("AuthQuickstart", result.isSignInComplete ()? "Iniciar sesión con éxito:" + result.toString ( ): "Iniciar sesión no completo"); if (result.isSignInComplete ()) {Toast.makeText (SplashActivity.this, "SignIn", Toast.LENGTH_LONG) .show ();}}, error -> Log.e ( "AuthQuickstart", error.toString ())); este mettod.

obtener un error es como W/AWSMobileClient: Failed to federate tokens during sign-in java.lang.RuntimeException: Error in federating the token. at com.amazonaws.mobile.client.AWSMobileClient$10.run(AWSMobileClient.java:1716) at com.amazonaws.mobile.client.internal.InternalCallback.await(InternalCallback.java:115) at com.amazonaws.mobile.client.AWSMobileClient.federatedSignInWithoutAssigningState(AWSMobileClient.java:1644) at com.amazonaws.mobile.client.AWSMobileClient$6$1.onSuccess(AWSMobileClient.java:1191) at com.amazonaws.mobileconnectors.cognitoidentityprovider.CognitoUser.getSession(CognitoUser.java:1020) at com.amazonaws.mobile.client.AWSMobileClient$6.run(AWSMobileClient.java:1176) at com.amazonaws.mobile.client.internal.InternalCallback$1.run(InternalCallback.java:101) at java.lang.Thread.run(Thread.java:761) Caused by: com.amazonaws.services.cognitoidentity.model.InvalidIdentityPoolConfigurationException: Invalid identity pool configuration.

Si está iniciando sesión para amplificar solo para obtener el token de acceso, entonces hay una forma más de obtener el token de un grupo de usuarios específico. Puede autenticar el grupo de usuarios usando el nombre de usuario y la contraseña y luego puede solicitar el token como se muestra a continuación:

public class AWSService {

public IdentityManager identityManager ;
public AWSCredentialsProvider credentialsProvider ;
public AWSConfiguration awsConfiguration;


public AWSService(Context context) {
    awsConfiguration = new AWSConfiguration(context);
    identityManager = new IdentityManager(context, awsConfiguration);
    identityManager.addSignInProvider(CognitoUserPoolsSignInProvider.class);
    IdentityManager.setDefaultIdentityManager(identityManager);
    credentialsProvider = identityManager.getCredentialsProvider();
}}




public static void getAccessToken(Context context, int requestCode, GetUserPoolTokenListener getUserPoolTokenListener) {


    AWSService awsService=new AWSService(context);

    CognitoUserPool cognitoUserPool=new CognitoUserPool(context,
            awsService.awsConfiguration);

    AuthenticationDetails authDetails = new AuthenticationDetails(PreferenceUtils.getStringPref(context,Constants.USER_NAME), PreferenceUtils.getStringPref(context,Constants.PASSWORD), null);

    final CognitoUser cognitoUser = cognitoUserPool.getUser();

    cognitoUser.initiateUserAuthentication(authDetails, new AuthenticationHandler() {
        @Override
        public void onSuccess(CognitoUserSession userSession, CognitoDevice newDevice) {
            Log.e("aws","onSuccess : "+userSession.getIdToken().getExpiration().getTime());
                        }

        @Override
        public void getAuthenticationDetails(AuthenticationContinuation authenticationContinuation, String userId) {
            Log.e("aws","getAuthenticationDetails : "+authenticationContinuation);
        }

        @Override
        public void getMFACode(MultiFactorAuthenticationContinuation continuation) {
            Log.e("aws","getMFACode : "+continuation);
        }

        @Override
        public void authenticationChallenge(ChallengeContinuation continuation) {
            Log.e("aws","authenticationChallenge : "+continuation);
        }

        @Override
        public void onFailure(Exception exception) {
            Log.e("aws","onFailure : "+exception);
        }
    }, true).run();
}
