Problem

When trying to replace a file in S3 using the upload endpoint, a duplicated key exception is thrown.

Reproducer

In S3 Upload Handler, if the code is modified to create two s3 binaries instead of one inside the tx, a ORecordDuplicatedException is thrown.

Expected behaviour

There should be only one S3 Binary for a specific objectKey and there shouldn't be duplicated records.

Actual behaviour

There can be more than one created S3 Binary Field with the same objectKey.
