I'm trying to save a new document in mongodb with mongoose, but I am getting ValidationError: Path 'email' is required., Path 'passwordHash' is required., Path 'username' is required. even though I am supplying email, passwordHash and username.

Here is the user schema.

    var userSchema = new schema({

      _id: Number,

      username: { type: String, required: true, unique: true },

      passwordHash: { type: String, required: true },

      email: { type: String, required: true },

      admin: Boolean,

      createdAt: Date,

      updatedAt: Date,

      accountType: String

    });

This is how I am creating and saving the user object.

    var newUser = new user({



      /* We will set the username, email and password field to null because they will be set later. */

      username: null,

      passwordHash: null,

      email: null,

      admin: false



    }, { _id: false });



    /* Save the new user. */

    newUser.save(function(err) {

    if(err) {

      console.log(Can't create new user: %s, err);



    } else {

     /* We succesfully saved the new user, so let's send back the user id. */



    }

  });

So why does mongoose return a validation error, can I not use null as temporary value?

In response to your last comment.

You are correct that null is a value type, but null types are a way of telling the interpreter that it has no value. therefore, you must set the values to any non-null value or you get the error. in your case set those values to empty Strings. i.e.

var newUser = new user({



  /* We will set the username, email and password field to null because they will be set later. */

  username: '',

  passwordHash: '',

  email: '',

  admin: false



}, { _id: false });
