Locating a user by their ID within a collection in Meteor can lead to some unexpected behavior

I have a requirement where I only want to allow users to insert a document if their email is verified. In an attempt to achieve this, I wrote the following code snippet.

Events.allow({
    insert: function (userId, doc) {
        var user = Meteor.users.find({_id: userId});
        console.log(user); // displays a large object
        // check if the user's email is verified
        if (user.emails[0].verified) {
            return true;
        }
        return false;
    }
});

Upon running this code, I encountered an "internal server error" and on further investigation on the server side, I got a

TypeError: Cannot read property '0' of undefined
, suggesting that there is an issue with my user object. To debug this, I logged the object and instead of seeing the expected user data, I was presented with a massive object structure as shown below:

{ _mongo:
    // myriad details
}

It appears that this is the top level mongoDB object utilized by Meteor.

The perplexing part is how Meteor.users.find({_id: userId}) returned the MongoDB object rather than the specific user I intended to retrieve?

If you're searching for a single result, consider using findOne instead of find. While find returns a cursor to the result set, findOne specifically returns the first matched document.
