I receive it when should be executed this loanAgreements = mapper.readValue(jsonResult, new TypeReference<List<LoanAgreement>>(){}); On previous vesions of core-model and server all was fine. Do you have any suggestions what could it be or how can it be solved?

This is full method

public static List<LoanAgreement> getLoanAgreements() {
        List<LoanAgreement> loanAgreements = new ArrayList<LoanAgreement>();

        String accessToken = TokenService.getAccessToken();
        String jsonResult = "";

        try {           
            jsonResult = ConnectorService.getGETResponse(accessToken, "loanagreements");
            JavaTimeModule module = new JavaTimeModule();
            module.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm")));
            module.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm")));
            ObjectMapper mapper = new ObjectMapper().registerModule(module);
                    mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
                    loanAgreements = mapper.readValue(jsonResult, new TypeReference<List<LoanAgreement>>(){});
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return loanAgreements;
}

I try to use edited JSON result. I removed all elements from cashCollaterals array. I know it's incorrect but it works.
