Console showing undefined when displaying the properties of a existing object

Question

var errors = validationResult(req);

console.log("errors: errors");

if (!errors.isEmpty()) {
  res.render('signIn-signUp', {
    'error1': errors.msg + " " + errors.value + " Please signUp again!!"
  });
} else {
  var id = 0;
  pool.query("Select Max(C_Id) as C_Id from customer", function(error, rows) {
        if (error) {
          console.log("Database error: ", error);
          res.render('signIn-signUp', {
            'error1': "database error: " + error + "please sign up again!"
          });

The above code is part of a nodeJs codebase. In the above code snippet, when I log errors object on console, it shows all the properties as:

errors: [{
  value: 'a',
  msg: 'Must be at least 5 char long',
  param: 'Password',
  location: 'body'
}]

but, when I display the individual properties of the object on the console, it is showing it as undefined. That is, console.log(errors.msg) is returning undefined. What is the reason for that?

How can I display the properties which exist in the object and are not undefined?

It seems that the errors object is an array (hence the [] ). Try this:

    console.log(errors[0].msg);
