Mongoose - Version Error: No matching document found for id

Question

Context: I have a Post Mongoose model that contains a csv_files array field to store csv strings. I make a fetch API

Answer 1

just to comment here what my problem apparently was.

Error Message:

message: 'No matching document found for id "5c86d3a15bbcb965d85d80d1" version 3', name: 'VersionError', version: 3

My code:

update: function (data) {

        var session = new Session(data);
        database.logging("INFO", "session-update", session.cid, session.order.orderNumber);
        return new Promise(function (resolve, reject) {

            session.save()
                .then(savedSession => resolve(savedSession))
                .catch(savedSessionError => reject(savedSessionError))
        });

    }

My parameter 'data' was already a Mongoose object and I was creating a new one and trying to save() it. So like @dacopenhagen said, save() checks the version of the document and it's throwing an VersionError error.

How I fixed it Just removing the creation of the Session() object. Removed this line

var session = new Session(data);

I hope this help.
