How to handle promise rejection in this case - node.js

Question

In here i want to add new field in collection User (User.facebook.botLink)
but i get an error.
Code where i get error looks like this:
app.post('/savelink/', async (req, res, next) => {
try{
console.log("================USER FACEBOOK ===============" + user.local.email)
const {link} = req.body;
console.log(link);
User.update(
{email: user.facebook.email},
{botLink : link},
{multi:true},
function(err, numberAffected){
});
res.status(200).send(link);
}
catch(e){
next(error);
}
});
Error i'm getting:
UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): ReferenceError: error is not defined
(node:6032) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

try this

You can aslo do a try/catch...finally.
Note that the finally block will be executed regardles of the result of try/catch.
