Hi I am building an app using Meteor and need to update my email address. I am using the Meteor accounts package. 

My form passes an email value into an accountDetails object, which I will pass into a method to update my profile (including my email):

```
Meteor.users.update({_id: this.userId},
{
   $set: {
            'emails.$.address': accountsDetail.email
    }

});

```

This gives me the error:

```
Exception while invoking method 'saveAccountInfo' MongoError: The positional operator did not find the match needed from the query. Unexpanded update: emails.$.address

```

Here is my user schema:

```
{
"_id" : "12345",

"emails" : [
    {
        "address" : "abc123@gmail.com",
        "verified" : false
    }

```

Can someone help? Thank you in advance!
