如何处理 mongodb+Node Js 中的断言错误？

Question

mongo.connect('mongodb://localhost',{useUnifiedTopology: true}).then((client) => {

        var db = client.db('complainbox');
        
                db.collection('admin').findOne({"Email":req.body.Email},(err,result)=>{
                   assert.equal(null,err);
                   assert.equal(req.body.Email,result.Email);
                   
                   assert.equal(req.body.Password,result.Password);
                   
                   console.log("found!!!!"+ result._id);
                   session.adminId=result._id;
                   
                   
                   res.redirect('/addstudent');
                   client.close();
                   
               });
         
           console.log('DB Connecmted!')
        }).catch(err => {
            
            
           // console.log(err);

        });

我的问题用这个方法解决了

            db.collection('admin').findOne({"Email":req.body.Email},(err,result)=>{
              try{ assert.equal(null,err);
               assert.equal(req.body.Email,result.Email);
               
               assert.equal(req.body.Password,result.Password);
               
               console.log("found!!!!"+ result._id);
               session.adminId=result._id;
               
               
               res.redirect('/addstudent');
               client.close();
              }
              catch(e){
                session.studentId=null;
                session.studentname = null;
                session.registration=null;
                session.Studentemail=null;
                session.adminId=null;
                  console.log(e);
                  res.redirect('/admin');
              }
               
           })
