cfn test returned model mismatch

[Nr18]

Hi, I am trying to create a cfn resource type in go. But the contract tests are failing on the following:

E    Request Model : {'MyBoolean': False, 'MyInteger': 10}
E    Returned Model : {'MyBoolean': 'false', 'MyInteger': '10'}
E    Value for property MyBoolean in Request Model(False) and Response Model(false) does not match

In the returned model the values are strings while the input is a boolean and an integer....

They are defined as:

{
    "properties": {
        "MyBoolean": {
            "description": "My description",
            "type": "boolean"
        },
        "MyInteger": {
            "description": "My description",
            "type": "integer"
        }
    }
}

Am I doing something wrong here? I am using cfn v0.2.32
