Spring boot Mongo on update: E11000 duplicate key error with #Version annotation - spring

Question

I have a Spring boot (v2.3.0.RELEASE) application with spring-data-mongodb (v3.0.0).
Basically when I add #Version annotation in my document, the application fails when I am trying to update an existing document and the code is as follows:
My document is as follows:
#Id
private String paymentId;
private String transactionId;
private String transactionTypeCode;
#Version
private Integer version;
My repository is as follows:
public interface PaymentRepository extends MongoRepository<Payment, String>, PaymentRepositoryCustom {
}
The update that fails is as follows:
Optional<Payment> paymentSaved = Optional.ofNullable(paymentRepository.findMaxIdByRefer(request.getAdd().getRefer()));
populatePayment(paymentSaved, payment);
paymentRepository.save(payment);
public static void populatePayment( Optional<Payment> paymentSaved, Payment payment) {
if (paymentSaved.isPresent() && !ObjectUtils.isEmpty(payment)) {
payment.setTransactionId(paymentSaved.get().getTransactionId());
payment.setCreationDate(paymentSaved.get().getCreationDate());
payment.setPaymentId(paymentSaved.get().getPaymentId());
}
}
The application fails on paymentRepository.save(payment) method with the following exception:
org.springframework.dao.DuplicateKeyException: E11000 duplicate key error collection: test.payment index: _id_ dup key: { _id: ObjectId('627a35b7f1ea29549008487e') }; nested exception is com.mongodb.MongoWriteException: E11000 duplicate key error collection: test.payment index: _id_ dup key: { _id: ObjectId('627a35b7f1ea29549008487e') }

It looks like it is trying to do an insert instead of update when I add the #Version annotation, any idea how i can resolve this issue please?
However, I cannot remove the #Version annotation.

Answer 1

I have found the issue basically on update the version was null that is why it was trying to create a new payment instead of update.I have retrieved the version from DB and now the update works fine.
