Null Pointer Exceptions

Please find attached a Cornoa Anamnese template. When trying to create the instance:

  public static CoronaAnamneseComposition buildCoronaAnamnese(){

        CoronaAnamneseComposition composition = new CoronaAnamneseComposition();
        composition.setLanguage(Language.DE);
        composition.setTerritory(Territory.DE);

        composition.setStartTimeValue(OffsetDateTime.of(2020, 04, 02, 12, 00, 00, 00, ZoneOffset.UTC));
        composition.setSettingDefiningcode(SettingDefiningcode.NURSINGHOMECARE);

        AnzeichenObservation observation = new AnzeichenObservation();
        observation.setSubject(new PartySelf());
        observation.setLanguage(Language.DE);
        observation.setBezeichnungDesSymptomsOderAnzeichensValue("Husten");
        observation.setOriginValue(OffsetDateTime.of(2020, 04, 02, 12, 00, 00, 00, ZoneOffset.UTC));
        observation.setTimeValue(OffsetDateTime.of(2020, 04, 02, 12, 00, 00, 00, ZoneOffset.UTC));
        observation.setVorhandenDefiningcode(VorhandenDefiningcode.NICHTVORHANDEN);

        AdHocUberschriftSection symptomeSection = new AdHocUberschriftSection();
        symptomeSection.setAnzeichen(observation);

        composition.setAdHocUberschrift(symptomeSection);

        //Set patient history
        HistorieObservation historyObservation = new HistorieObservation();
        historyObservation.setOriginValue(OffsetDateTime.of(2020, 04, 02, 12, 00, 00, 00, ZoneOffset.UTC));
        historyObservation.setSubject(new PartySelf());
        historyObservation.setLanguage(Language.DE);

        GeschichteHistorieBeliebigesEreignisPointEvent event = new GeschichteHistorieBeliebigesEreignisPointEvent();
        event.setTimeValue(OffsetDateTime.of(2020, 04, 02, 12, 00, 00, 00, ZoneOffset.UTC));
        GeschichteHistorieGeschichteElement geschichteElement = new GeschichteHistorieGeschichteElement();
        geschichteElement.setValue("Patient fuhr zum Skifahren nach Ischgl und kam krank zurück");

        List<GeschichteHistorieGeschichteElement> geschichtEventListe = new ArrayList<>();
        geschichtEventListe.add(geschichteElement);
        event.setGeschichte(geschichtEventListe);

        List<GeschichteHistorieBeliebigesEreignisChoice> historyObservationList = new ArrayList<>();
        historyObservationList.add(event);
        historyObservation.setBeliebigesEreignis(historyObservationList);

        List<HistorieObservation> historyObservations = new ArrayList<>();
        historyObservations.add(historyObservation);

        composition.setHistorie(historyObservations);

        //Allgemeine Angaben

        AdHocUberschriftSection4 section4 = new AdHocUberschriftSection4();

        DiagnoseEvaluationProblem diagnose = new DiagnoseEvaluationProblem();
        diagnose.setDerDiagnoseValue("Freitextdiagnose");
        diagnose.setLanguage(Language.DE);
        diagnose.setSubject(new PartySelf());

        List<AdresseDiagnoseChoice> diagnoseEvaluationList = new ArrayList<>();
        diagnoseEvaluationList.add(diagnose);
        section4.setDiagnose(diagnoseEvaluationList);
        composition.setAdHocUberschrift(section4);

        return composition;
    }

I get the following exception:
