Mongoose array object maxlength validation not working

I have the schema below that is allowing me to create a user with a badge of "1234567" for an existing app. I expected to receive a validation error b/c of the maxlength validation.

Is there something wrong with my schema?

module.exports = function(db) {
    var mongoose = require('mongoose');

    var appSchema = mongoose.Schema({
        name: {
          type: String,
          required: true,
          unique: true,
        },
        settings: mongoose.Schema.Types.Mixed,
        user: [{
          badge: {
            type: String,
            minlength: 5,
            maxlength: 5
          }
        }]
    });

    // Export the schema for the app to use
    return db.model('apps', appSchema);
}

I'm trying to use 

apps.findByIdAndUpdate(req.params.id, {$push: {user: req.body.user}}, {runValidators: true},callback());

to add a new user record to the array in an app document.

Validators will only work on updates for $set and $unset operations, so I believe you will have to validate manually before the update in this case.

As from docs, mongoose requires an Schema to validate nested objects.

so your schema should be defined as such.

Can you try using the following definition instead?

var userSchema = mongoose.Schema({
    badge: {
      type: String,
      minlength: 5,
      maxlength: 5
    }
});

var appSchema = mongoose.Schema({
    name: {
      type: String,
      required: true,
      unique: true,
    },
    settings: mongoose.Schema.Types.Mixed,
    user: [userSchema]
});
