Glad UpdateAttribute works for you. You are seeing AttributeToJson append the information to the content? That is not what the documentation says or how it should be behaving (should replace the contents). Could you send more information documenting this?

Also is it possible to push only the attributes to Mongo? I could see an AttributeToJson object but it seems to be appending the information in flow file content or attribute. What is a good way to capture only attributes and send it to MongoDb?
