Description

The RunMongoAggregation processor uses Jackson to serialize the document to JSON. However, the default serialization for Jackson on Mongo ObjectId and dates leaves a lot to be desired. The ObjectId's are serialized into the decimal representation of each component of the ObjectId instead of the hex string of the full byte array. Mongo dates are being serialized as unix time as opposed to ISO8601 zulu string.

It looks like the GetMongo processor has set the correct serializer flags on Jackson to fix this. The fix for GetMongo is here. https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-mongodb-bundle/nifi-mongodb-processors/src/main/java/org/apache/nifi/processors/mongodb/GetMongo.java#L213
