I set up a very basic test

function MyError(msg){
    this.name = 'MyError';
    this.message = msg;
    Error.call(this, msg);
    Error.captureStackTrace(this, this.constructor);}
MyError('New error')

And that works fine.

However in my full app, I hit the below issue. Is there someway I could 
have mashed captureStackTrace in my code set? I grepped it, and there 
aren't any obvious missuses of the name.


I'm trying to use validation provided by Mongoose, so have a scheme

var MeecaptureStackTracetingSchema = new Schema({
 title: {type: String, required : true}....

Trying to save without setting the title - gets to the below point, 
Mongoose wants to return the error for the missing fields but falls over 
with " no method 'captureStackTrace'"

/mongoose/lib/error.jsfunction MongooseError (msg) { // Validator "required" 
failed for path title with value `undefined`
  Error.call(this);
  Error.captureStackTrace(this, arguments.callee); // Falls over here
  this.message = msg;
  this.name = 'MongooseError';};

Throws this error

TypeError: Object function model(doc, fields, skipId) {
    if (!(this instanceof model))
      return new model(doc, fields, skipId);
    Model.call(this, doc, fields, skipId);
  } has no method 'captureStackTrace'


Thanks,

Brent
