mongoose: why I'm not getting error response

I wrote this route to find user every time I'm entering wrong user I didn't getting res.json() msg

app.post('/authenticate', function(req, res){

    user.findOne({email : req.body.username}, function(err, user){
          if(err){
            res.json('user not found');  //not getting this 
          }else{  
            console.log(user);  //probably this ran, cuz getting null at cmd
          }
    })
})

When username doesn't match with any of document , it returns empty user json . Error err object is null so res.json is unreachable , so you have to handle this by 

app.post('/authenticate', function(req, res){

        user.findOne({email : req.body.username}, function(err, user){
              if(err){
                throw err;
              }else{ 
                if(user){
                  console.log(user);  //probably this ran, cuz getting null at cmd
                }else{
                  console.log("User Not Found");
                }

              }
        })
    })
