MongooseError: Model.findOne() no longer accepts a callback ... fixed using then and catch instead of use if and else method

[UmitRock]

use new code of login post

 app.post("/login",function(req, res){
 const username = req.body.username;
 const password = req.body.password;

 User.findOne({email:username})
 .then(function(foundUser) {
     if(foundUser){
         if(foundUser.password === password){
             res.render("secrets");
         }
     }
})
.catch(function(err) {
 console.log(err);
});

});

instead of old code of login post

app.post("/login", function(req, res){ const username = req.body.username; const password = req.body.password; User.findOne({email: username}, function(err, foundUser){ if (err) { console.log(err); } else { if (foundUser){ if (foundUser.password === password){ res.render("secrets"); } } } }); });
