Getting parameter from a request

Hi! I’m trying to get a parameter value from an HTTP request that is generated randomly. This is my code:

#create auth user
# @name createUser
POST {{authServiceUrl}}/api/v1/users
content-type: application/json

{
    "email": "test-{{$guid}}@example.com",
    "passwordhash": "XXX"
}

@email = {{createUser.request.body.$.email}}

As a result I get the error:

Unexpected token @ in JSON at position 187

What is the correct way to do it?

Thanks in advance

### create auth user
# @name createUser
POST {{authServiceUrl}}/api/v1/users
content-type: application/json
 
{
     "email": "test-{{$guid}}@example.com",
     "passwordhash": "XXX"
}

### 
@email = {{createUser.request.body.email}}

1. Insert ### before @email =
2. and, in this case, without $

Yes, it works!
