Mongoose Schema Error: “Cast to string failed for value” when pushing object to empty array

Question

I have a strange problem and cannot figure out what the problem is. The Error-message doesn\'t help.

I\'m sending an "alarm" to the server and want to save

Use inner schema to solve this,

var SchemaObject = require('node-schema-object');

// Create custom basic type 
// Type can be extended with more properties when defined 
var NotEmptyString = {type: String, minLength: 1};

// Create sub-schema for user's Company 
var Company = new SchemaObject({
  startDate: Date,
  endDate: Date,
  name: NotEmptyString
});

// Create User schema 
var User = new SchemaObject({
  // Basic user information using custom type 
  firstName: NotEmptyString,
  lastName: NotEmptyString,

  // "NotEmptyString" with only possible values as 'm' or 'f' 
  gender: {type: NotEmptyString, enum: ['m', 'f']},

  // Index with sub-schema 
  company: Company,

  // An array of Objects with an enforced type 
  workHistory: [Company],

  // Create field which reflects other values but can't be directly modified 
  fullName: {type: String, readOnly: true, default: function() {
    return (this.firstName + ' ' + this.lastName).trim();
  }}
});

// Initialize a new instance of the User with a value 
var user = new User({firstName: 'Scott', lastName: 'Hovestadt', gender: 'm'});

// Set company name 
user.company.name = 'My Company';

// The date is automatically typecast from String 
user.company.startDate = 'June 1, 2010';

// Add company to work history 
user.workHistory.push({
  name: 'Old Company',
  startDate: '01/12/2005',
  endDate: '01/20/2010'
});

console.log(user.toObject());

// Prints: 
{ firstName: 'Scott',
  lastName: 'Hovestadt',
  gender: 'm',
  company: 
   { startDate: Tue Jun 01 2010 00:00:00 GMT-0700 (PDT),
     endDate: undefined,
     name: 'My Company' },
  workHistory: 
   [ { startDate: Wed Jan 12 2005 00:00:00 GMT-0800 (PST),
       endDate: Wed Jan 20 2010 00:00:00 GMT-0800 (PST),
       name: 'Old Company' } ],
  fullName: 'Scott Hovestadt' }
