Description

I have registered a MappingMongoConverter component to perform custom conversions for all document reads and writes. When performing find / findOne / etc. operations, this works as expected. However, when using ReactiveMongoTemplate::findAndReplace, the conversion is not applied on the returned document (the MappingMongoConverter::read method is not called). Is this expected behavior? Thanks in advance!

Research direction

Start with ReactiveMongoTemplate::findAndReplace and compare the returned-document path with the find and findOne paths where MappingMongoConverter::read is called. Reproduce the custom-conversion case described in the issue and verify that the returned document is converted before treating the behavior as fixed.
