question largely for @mbarton
The response object error has changed a little with this PR:

{
    "detail": [
        {
            "loc": [
                "body"
            ],
            "msg": "Error: The paternal height is < -6 SD. Please check the accuracy of the paternal height and try again.",
            "type": "value_error",
            "input": "height_paternal"
        },
        {
            "loc": [
                "body"
            ],
            "msg": "Error: The maternal height is < -6 SD. Please check the accuracy of the maternal height and try again.",
            "type": "value_error",
            "input": "height_maternal"
        }
    ]
}

Here the detail element is now a list rather than a single object, in case both parameters (height_paternal and height_maternal) have errors. As goes the @mbarton spidey sense - is this a minor version change or a patch (here it is just a patch).
