Getting the ID of document affected by upsert

Hi

I am upserting a document like this

       let conversation = {
          contextGraphId: graph.graphId,
          authorGraphId: posting.authorGraphId,
          authorName: posting.authorName,
          authorScreenName: posting.authorScreenName,
          authorThumbnail: posting.authorThumbnail,
          service: posting.service
        };

        let selector = { service: posting.service, authorGraphId: posting.authorGraphId };
        let conversationId = Conversations.upsert(selector, { $set: conversation }); <------------- Offending line
        
        posting.conversationId = conversationId
        Postings.insert(posting);

Problem is that the Conversations.upsert only returns an ID upon insertion. I also want to retrieve the ID in the case that the document was updated.

Is there any way to accomplish this without resorting to a seperate find query?

Thanks

I don’t think so (same thing with update).

Unfortunately, as stated in the documentation here, in case of an update, it only send back the number of documents updated by the query. You’ll have to get it with a separate query.
