Mongo Expert for NodeJS Backend project

Hi I have a small issue I'm trying to update the [login to view URL] value of this array in mongo.

Using this:

await [login to view URL](

{ "[login to view URL]": req.user._id },

{ $set: { "lastSeen.$.date": [login to view URL]() } }

);

My document structure is attached ([login to view URL]). I just need to know the fix for this. If you're good, I would like to have you optimize and refactor my backend which uses Mongo/Mongoose.

Kĩ năng: NoSQL Couch & Mongo, node.js, MongoDB
