msg.limit and msg.sort do not work with mongodb2

example with msg.limit=2 , mongoDB2 retrieves 5 documents

Why should they work? The node only looks at the parameters passed in msg.payload

vcailly commented 6 years ago

it was working with mongdb node. So can you tell me how I can pass the limit value and the sort object in msg.payload. i did not find how to do it.

You should set msg.payload to an array of parameters that will be passed to the chosen mongodb command. see: http://mongodb.github.io/node-mongodb-native/2.2/api/Collection.html
