[@nativescript/biometrics] - Android: ".pinFallBack: false" returns javax exception

Inizia con l’implementazione Android di @nativescript/biometrics e il percorso verifyBiometric, riproducendo i passaggi elencati con pinFallback impostato su false. Esamina il fallimento di onAuthenticationSucceeded che coinvolge javax.crypto.IllegalBlockSizeException; il lavoro è completato quando un’autenticazione tramite impronta digitale riuscita non produce più questa eccezione in questa configurazione.

General Info:

Android minSdk: 26
Android Emulator Sdk: 33
Plugin Version in package.json: ^1.3.1

JS Code in main-page.js

const biometricAuthPlugin = require('@nativescript/biometrics');
const biometrics = new biometricAuthPlugin.BiometricAuth();

biometrics.verifyBiometric({
                title: 'Speichern der Anmeldedaten',
                message: 'Anmeldedaten werden gespeichert bzw. überschrieben und in Zukunft zur schnelleren Anmeldung automatisch ausgefüllt.',
                fallbackMessage: 'Bitte PIN eingeben',
                pinFallback: false,
            }).then(function (result) {
                if (result.code === 0 || result.message === "All OK") {
                    AppSettings.setString("username", eventData.username);
                    AppSettings.setString("password", eventData.password);
                } else {
                    console.warn("Sonderfall Authentifizierung (erfolgreich aber nicht Code 0):", result);
                }
            }).catch(function (error) {
                if (error.code === 50 || error.message === "Authentication canceled") {
                    console.log("Authentifizierung durch Nutzer abgebrochen");
                } else {
                    console.warn("Fehlerfall bei der Authentifizierung:", error);
                }
            });

This is inside a function which responds to an Event in a WebView. eventData is provided by this function. This function is not the source of the problem, it always worked.

Steps:

1. Start Auth. process
2. Android Window Pops up
3. Touch Fingerprint Sensor, Android confirms Fingerprint
4. Error in onAuthenticationSucceeded: Error: javax.crypto.IllegalBlockSizeException

Might this be a problem of my installed Java-Version?
I checked that the usage of ü, ö, ä is not the Problem (Why ever this should be a problem, UTF-8 supports umlauts/mutations after all)
