Create HIT MTURK from an existing template

I use the Python AWS boto v2.7 package to interact with the Mturk API to create and manage HIT, etc.

I am trying to create a HIT using an existing template. Amazon's documentation on this topic is here: http://docs.aws.amazon.com/AWSMechTurk/2012-03-25/AWSMturkAPI/ApiReference_CreateHITOperation.html

My code is:

from boto.mturk.connection import MTurkConnection

mtc = MTurkConnection(aws_access_key_id=ACCESS_ID,
                             aws_secret_access_key=SECRET_KEY,
                             host=HOST)

mtc.create_hit(hit_layout=HIT_LAYOUT_ID)

Error:

MTurkRequestError: MTurkRequestError: 200 OK
<?xml version="1.0"?>
<CreateHITResponse><OperationRequest><RequestId>986926dd-0263-4aca-970c-139b7ed4a0e8</RequestId></OperationRequest><HIT><Request><IsValid>False</IsValid><Errors><Error><Code>AWS.MechanicalTurk.InvalidParameterValue</Code><Message>There was an error parsing the request (1359492767224 s)</Message></Error></Errors></Request></HIT></CreateHITResponse>

It looks like the MTurk API is expecting a layout parameter, as described here: http://docs.aws.amazon.com/AWSMechTurk/2012-03-25/AWSMturkAPI/ApiReference_HITLayoutArticle.html

While my original template used placeholder values, I deleted them for simplicity and just tried to get the code to work. In this case, I would have thought that the only required parameter would be hit_layout?
