mongoose TypeError: Schema is not a constructor

I've encountered a strange thing. I have several mongoose models - and in one of them (only in one!) I get this error:

TypeError: Schema is not a constructor


I find it very strange as I have several working schemas. I tried logging
mongoose.Schema
in the non-working schema and it is indeed different from the mongoose.Schema in my working schemas - how is that possible? The code is almost identical.
Here's the code for the non-working schema:

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var errSchema = new Schema({
name: String,
images:[{
type:String
}],
sizes:[{
type: String
}],
colors:[{
type: Schema.ObjectId,
ref: 'Color'
}],
frontColors:[{
type: Schema.ObjectId,
ref: 'Color'
}],
script: Boolean
},{
timestamps: true
});

var Err = mongoose.model('Err', errSchema);

module.exports = Err;


Code for a working schema:

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var colorSchema = new Schema({
name: String,
image: String,
rgb: String,
comment: String,
});

var Color = mongoose.model('Color', colorSchema);

module.exports = Color;


Any help would be appreciated!

Answer

It should be Schema.Types.ObjectId, not Schema.ObjectId: http://mongoosejs.com/docs/schematypes.html
