controller :

app.get(\"/update\", (req, res) => {

console.log(req.query);

users.replaceUser(req.query._id, req.query.name, req.query.age, req.query.email, req.query.phoneNumber)

.then(updateCount => {

console.log(updateCount);

res.send({ updateCount: updateCount });

})

.catch(error => {

console.error(error);

res.send({ error: 'Request failed' });

});

});

model:

const replaceUser = async (_id, req) => {

const result = await User.findOneAndUpdate({ _id: req.query._id}, req.query);

return result.nModified;

I am unfamiliar with JavaScript and cannot get this to work: I keep getting this error TypeError: Cannot read property 'query' of undefined
