Node.js res.end contents are sent in res.config.data instead of res.data

Front end guy going fulls tack here... can't figure out why my response values end up in res.config.data instead of res.data. Below is my code.

  addEngineer(req, res) {      MongoClient.connect(url, function (err, client) {        let finalRes;        if (err) {          throw err;        } else {          let db = client.db(dbName);          db.collection("Engineers")            .insertOne({              Name: req.body.name,              Email: req.body.email,              Status: req.body.status,              Specialty: req.body.specialty,            })            .then((result) => {              finalRes = result;              console.log(result);            });          client.close();        }        res.status(200).end(finalRes);      });    },
