I have an issue when update a form in Spring boot - spring

Question

I want to update a form in spring boot - all input fields are successfully populated from the retrieved data but when I press 'submit' for update the system gives this error message.
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
For input string: "updateApplication"
My DAO code:
public interface SLSNotificationRepository extends CrudRepository<SLSNotification, Integer> {
#Override
SLSNotification save(SLSNotification slsNotification);
#Override
SLSNotification findOne(Integer integer);
#Override
long count();
#Override
void delete(Integer integer);
#Override
void delete(SLSNotification slsNotification);
#Override
void delete(Iterable<? extends SLSNotification> iterable);
#Override
List<SLSNotification> findAll();
#Query("select a from SLSNotification a where a.slsiUnit in :unitList")
List<SLSNotification> getApplicationsByUnit(#Param("unitList")List <String> unitList);
#Query("select a from SLSNotification a where a.userId = :userId")
List<SLSNotification> getApplicationsByUserId(#Param("userId")String userId);
#Query("select a from SLSNotification a where a.slsNo = :slsNo")
SLSNotification getApplicationBySLSNumber(#Param("slsNo") String slsNo);
#Query("select a from SLSNotification a where a.importerVAT = :importerVAT group by slsNo")
List<SLSNotification> getproductByUserId(#Param("importerVAT")String importerVAT);
}
My service:
public boolean update(SLSNotification slsNotification) {
serviceLogger.info("Staring adding/updating the SLS Notification data . data : [{}]", slsNotification);
try {
serviceLogger.info("Saving data in the database. [{}]", slsNotification);
slsNotificationRepository.save(slsNotification);
return true;
} catch (Exception e) {
serviceLogger.error("Error occurred while saving SLS Common data . [{}]", e);
rollBack.rollback();
return false;
}
}
My controller is
#RequestMapping(path = "/updateApplication", method = RequestMethod.POST)
public String updateApplication(#ModelAttribute("applicationForm") #Valid SLSNotification slsNotification,
BindingResult result,
HttpSession session) {
slsiLogger.info("Request received to register new product. [{}]", slsNotification);
if (result.hasErrors()) {
slsiLogger.error("Rejecting the request due to binding errors, [{}]", result.getFieldErrors());
return "redirect:/applicationManage?";
}
if (applicationServices.update(slsNotification)) {
slsiLogger.info("Product registered successfully");
session.setAttribute(MESSAGE_KEY, "Product registered successfully");
} else {
session.setAttribute(MESSAGE_KEY, "Error occurred while registering the product");
}
return "redirect:/applicationManage?" + MESSAGE_KEY;
}
My JSP:
