We're having substantial struggles utilizing the source connector "out-of-the-box" because it is not able to convert binary (subtype=4) UUID values to hexidecimal string form like it does for OIDs when using the SimplifiedJson JsonWriterSettingsProvider.

This could be easily remedied with a conversion for Standard UUIDs included in the provider like

.binaryConverter(
    (value, writer) -> {
        if (BsonBinarySubType.UUID_STANDARD.getValue() == value.getType())
            writer.writeString(value.asUuid().toString());
        else
         writer.writeString(Base64.getEncoder().encodeToString(value.getData()));
})
